Thinking of selling my 7 pro for a s23u that galaxy looks quite impressive great screen great battery life and cameras
As I now have both I can say a few things.
I love my Pixel 7 Pro and through the sale Google had and high trade in value for my old iPhone the phone was essentially free. I was also able to snag the ultra for a really good deal so cost between the two is not an issue I will discuss although there is a considerable difference if you are paying full retail price for either phone.
I will go over some basics then talk UI.
The two phones are almost identical in size yet the thickness of the s23 ultra is definitely bigger. The slim bezels on the s23 make the 6.8" screen take up most of the space. The P7P has slightly thicker bezels all around. The curvature of the glass on the P7P is also more pronounced leading to a very minimal distortion on the edges of the display that you don't see on the Ultra.
Out of the box the Pixel display looks more balanced and natural. The P7P has one of the best color temperature profiles I have seen. You can tweak the s23u to get very close but the P7P has a slight advantage here. The resolution feels identical on both even though the s23u is slightly higher. Both screens are really nice but the s23u has a slight edge in size and brightness, smaller bezels and less curved display.
The speed or processor is where you start to see some larger difference. The SOC on the P7P is good and in most cases there is little delay but on Facebook or other sites there can be some waiting while things load but it is minimal. Launching apps is fast on P7P and UI is very smooth. Animations are also very smooth. BUT the s23u takes things to another level. To say that it is the fastest Android phone I have ever used is no stretch here. Everything is super fast. Websites have no delay, update installations are incredibly fast, apps load super fast. UI animations and transitions are super smooth. There is a noticeable difference in the speed of the s23u.
Speakers on both phones are very good. The Pixel has more bass than most phones I have used. Compared to the s23u it is still slightly better. However overall volume and stereo separation is better on the s23u. The s23u speakers are very good. It is close but again the s23u has an edge.
Battery life. The P7P has decent battery life but every once and a while something seems to cause high drain. The P7P is a all day phone for heavy use and a 2 day phone for light use. The s23u is again better here. It is a 2 day phone with heavy use and longer for light use. It just seems the s23u is more efficient overall no matter what you do.
Graphics performance of the Tensor G2 is good. No one is going to complain they can't play games on the P7P. However the s23u has a big advantage here. The GPU on the ultra is significantly better. Cooling of the Ultra is significantly better than the Pixel 7 Pro. So if gaming or high GPU related tasks are important the s23u is much better.
Cameras on both phones are excellent but Samsung has really done a good job improving the focus related shots and speed related shots than in the past. Combined with higher resolution sensors and higher zoom it is very well matched. I would say with Pixel exclusive features like photo unblur and better AI post processing that the Pixel has the better camera system but Samsung has focused on reducing the gap between the two.
Build quality. Both phones have excellent build quality and you would be hard pressed to complain about either but the s23u is simply a more refined build. The seams are non existent on the s23u while the seams on the P7P are noticeable along the screen. The weight is almost the same and while the P7P feels great in the hand the s23u with it's thicker sides just seems easier to grip. The corners of the s23u might be a little sharper it is still comfortable and the more squared design gives maximum usable space on the screen. The P7P has an iconic look that I prefer to the s23u but the s23u has a unique look and is a bit better made.
The UI itself and the AI skills that Google adds to the Tensor G2 and Pixel 7 series is a big part of the selling point of the Pixel series. In fact it is probably the biggest selling point besides the camera system. Google doesn't disappoint either. The system UI is extremely responsive, stable and refined. Animations are smooth and fun. The speech to text is the best of any UI. The call screening is superb. The other AI features, slim Android build, fast updates, and other unique features make the Pixel 7 Pro more than the sum of its parts.
I would even go so far as to say besides the Samsung s23 ultra it is the most advanced phone out there. The Samsung s23 ultra is not that far behind with their own call screening, better computational AI in the cameras, and OneUI 5 although still a bit bloated is much refined with no stutters. The amount of features like Dex, the sPen, and customization on the s23u is unmatched by any other phone.
So I would say that the two phones are pretty close to one another. There are some advantages of the Pixel and some advantages of the s23u.
If I had to pick only one phone I would probably go with the s23u simply for the longer OS upgrades, the better all around hardware and super fast processor. I like the more rectangular design that allows better use of the screen. The spen is like the cherry on top.
If you are a specs nerd like me then you will also appreciate that everything on the s23u is cutting edge stuff. UFS 4.0 storage is about twice as fast as ufs 3.1 with close to 50% less power draw. Ddr5x is about 30% faster with the same power draw, the screen is brighter with better efficiency, the processor is faster with better efficiency, the camera setup is improved. Literally everything is the best on the s23u.
The Pixel 7 Pro on the other hand takes a more tried and true approach where the components might not be the latest and greatest and good enough. With an emphasis on software and AI the Pixel manages to feel just as fast and responsive in most scenarios as the s23u.
So I think it really comes down to budget and personal preference. Both are incredible phones and you can't go wrong with either.
