So I was wondering if you use apps that are available on both MacOS and Windows platforms, what were your reasons for choosing Mac?
A lot of it simply comes down to whether you prefer MacOS or Windows - I think MacOS is still slicker, more consistent and more responsive than Windows - but maybe not so much as back in the Good Old Bad Old Days. Neither Apple or Windows are immune to the modern problem with dumbed-down software design and form-over-function "user experiences". Reality is that 90% of the computing world manages to get their work done on Windows and, as you say, a lot of the time you end up running the same applications.
Personally, I also like the Unix underpinnings - but that's not going to be an issue for people who never open Terminal or write a shell script. In the past, the combination of Unix + all the usual open source server tools, a far nicer GUI than Linux plus the ability to run "industry standard" software like MS Office and Adobe CS (if only to handle material that you are sent) made Mac a winner for Web development, esp. if you were targeting Linux/Unix servers, - but, increasingly. modern practice is to use VMs and containers.
Hardware wise - if you want small, thin, quiet, light laptops with decent battery life (or small-form-factor/all-in-one desktops) but enough performance for "pro" applications, Apple Silicon is going to be kicking sand in Intel/AMD's faces for a while. If you
don't mind having a hefty, mains-tethered laptop that doubles as a room heater - maybe you only ever carry it to and from the car and always use it on a desk - then that advantage fades, and if you want a good old fangled desktop mini-tower with PCIe slots, Apple's range currently
sucks. (I'm waiting to be swayed by the Apple Silicon 5k iMac replacement/Mac Mini Pro/Mini Mac Pro/whatever - but once you go to a larger desktop where power/heat isn't such an issue, Apple Silicon is going to have a harder time proving itself).
With audio production, I think Apple has a reputation for doing better with audio and MIDI, with less driver hassle, better latency etc. (& with things like creating composite interfaces and virtual MIDI busses baked in to the OS) but I don't really have the evidence to defend that. Logic Pro is a well-respected, widely supported app (...and also relatively cheap c.f. the fully-featured versions of Ableton, Bitwig etc. with GarageBand as the free tier vs. the various cut-down versions of Ableton - something to offset against the extra cost of a Mac). All DAWs are pretty complex programs with a massive learning curve, so if you're up to speed on Logic you have to consider the human cost of switching to something else.
Then, of course, if you're bought into the iPhone/iPad/Watch/Music ecosystem, the Mac is better integrated.
However the #1 rule is
buy the hardware that runs the software you want to use - and in this case that probably means doing the research to see which OS has the best implementation
for you. E.g. MS Office on Mac is significantly cut-down from Office for Windows (Access, Project, Publisher completely missing & some Excel features missing last time I looked...) although many people simply don't need/use those features. Other pro apps may be better implemented on Mac (you'd need to ask the specific forums...)
