Yeah, I FINALLY found someone on YouTube that compared the 2013-era rMBP and they are almost identical in size (thickness, aside). I think I’m leaning towards the 16, but somewhere deep down I wish I could justify the smaller screen. I just think I’ll feel cramped on the smaller screen, even if I use the iPad as an external monitor at times.
I have gone through this dilemma as well. My background is that I own an 11 inch MacBook Pro which I replaced after briefly buying the 12.9 inch and finding while it was very good as a laptop sized replacement it was not very comfortable to use being too cumbersome as a tablet I did buy the extra magic keyboard with it and in a pinch it can be used for productivity as a very mini laptop. As far as owning laptops are concerned, I did on the 2012 retina MacBook Pro which still works and other than poor battery life the fans going all the time and processing power not being anywhere close to current specs is still a remarkable machine for its design it's screen quality and everything else. In the interim in 2018 I had decided to switch to Windows and bought a surface book 2. This was a 13 1/2 inch machine and 3 1/2 pounds in size. It has a 3 x 2 screen configuration which probably puts it similar in overall size to the 14 inch MacBook Pro which uses a 16 x 10 resolution dimension. Overall I really did enjoy this as a laptop it had a lot of great things about it but I find I was missing some performance some battery life and while the screen was really good it did have a fair bit of backlight bleed which was evident when doing some video watching at night time as the shape of the screen leads to more black bars at the top and bottom then a 16 x 9 or 10.
I was not interested in buying a Mac laptop with the terrible keyboard problems they had up until the MacBook M1 series of chips. And as such I have been sticking with my surface book. When using my MacBook Pro from time to time I did enjoy the larger screen for certain work and certainly the immersive affect a video watching on it. However as the screen technology has improved the 900 to 1 contrast ratio was certainly not as good for multimedia.
With the announcement of the new MacBook Pro in 14 and 16 inch and in particular with that spectacular mini LED monitor I decided it was finally time to make the leap and come back to Apple as my main laptop. I was quite indecisive and watched a ton of videos to help me make my decision between the 14 and the 16 knowing I have laptops at home of both sizes and weights. I still was having trouble deciding as they were significant pros and cons on each side of the balance sheet.
The price difference was not going to be that much in the sense that I would not get the most base spec bend 14 inch but would certainly go for the 10 core CPU 16 core GP 1 TB option. The 16 inch and 14 inch were in US dollars $200 different and the AppleCare was another $120 difference. This was not a factor in my decision making.
Basically from all I read and all the reviews it essentially came down to these two deciding factors:
In favour of the 14 inch was a lighter and smaller form factor. I suppose if you are a student or somebody who uses their laptop while commuting I can see these being big benefits as you can get more work done in tighter spaces such as plane or train seat tables. However partly due to Covid and partly due to a job that does not involve travelling most of my travel when it does occur is for vacation purposes where outside of perhaps watching some video on my computer I would not be using it for productivity. I also happen to own an 11 inch MacBook Pro and while that screen does not have the gorgeous mini LED, it is still more than sufficient for video watching on a plane.
In favour of the 16 inch:
1.Longer battery life- upward of 25 to 30% or in practical terms 3-5 hours use
2.Much bigger screen which would allow for more immersive video watching as well as more real estate to work on documents side-by-side or for light video or photo editing allowing more to be done with a bigger canvas
3. Improved speakers which while not getting used all the time would be good for media watching we're not using headphones or earbuds and with Dolby Atmos spatial audio it definitely gives a very good experience.
4. Better heat and thermals. This doesn't sound like very much but the truth of the matter is that the fans almost never have to come on and the rare instances where people have reported them coming on being that they are bigger and spinning at a lower speed they are nearly inaudible over the background noise in a room compared to the fans on the 14 inch.
So for my used case I opted for the 16 inch. My rationale is that I don't have a lot of circumstances that require me to do work away from home. And truth be told if I was to go to a coffee shop to surf the web and go through some emails I would probably just prefer to take an 11 inch MacBook Pro that I don't mind if it gets banged around a little bit rather than my machine that cost triple the price. If I really need to take it to work it is no different in size dimensionally than my 15 inch MacBook Pro from 2012 and only weighs .2 pounds more which is marginal. There is a savings benefit in that the battery life is so incredible that I do not need to take the charger with me where is perhaps if I needed the computer to work on for the whole day at work I might need to bring it with which does add weight and bulk.
I also currently don't own a second monitor. We do have a very old iMac from 2011 which these days is merely sufficient for some web browsing word processing an email but would not be used for heavier tasks and as such this would be my every day computer with only using the screen that I have. The screen is so fantastic I would not have any desire to hide it in a clamshell mode attaching it to a larger monitor. I think anybody who would consider doing that would be better off just waiting for a Mac mini with an M1 Pro chip in it and just get themselves a MacBook Eyre and they would still be a head pricewise.
So I apologize for this really long post but I think it basically highlights my thought process that could be helpful to you and anyone else reading this thread. In summary my TL
R if you need to commute and work on the road where form factor is the most important thing and get the 14 inch. However if this is going to be your main computer and used as much or more at home than anywhere else without external monitor use I would say the 16 inch is the better bang for the buck in terms of screen size overall battery life sound and performance and it's still a reasonable weight for what you get without incurring significant additional cost.
