I hesitated a lot whether to go for the MacBook Air 15" or Pro 14", but in the end I opted for the pro and I don't regret it for a moment. The Pro feels a bit 'clunky' compared to the Air, but I think this is a positive.
The screen of the 14" Pro is ideally sized, while I found it just too small on my previous Pro (13"). The screen quality of this MacBook Pro is phenomenal: crystal clear and you can see enough outside during the day even in sunny weather.
The color space black is, in my opinion, a very luxurious version, and is much less sensitive than the midnight of the Air.
A small pity is that the charging cable is made in space black, but they do not extend this line to the adapter (which is still white), Apple could have done more with this. Anyway, then we are already talking about very small details.
In terms of speed and smoothness, this M3 pro chip is a winner.
As a tip I can give you very good information about the different versions, because there are some, too many in my opinion.
