I'm one of those rare people that like Gnome 3 way better than Gnome 2 or any other "windows 95" or "traditional-style" desktop. Other than command-line apps, I run like 5 main pieces of software regularly (IDE, browser, etc.) and probably 20 pieces of gui software total over the lifetime of my PC. I want something that:
1. Makes it easy to launch my main 5 apps (under 1 second)
2. Makes it fairly easy to run the 15 apps I run less often (couple secs max)
3. Looks pretty out of the box w/o customization so I can just get stuff done
The only environments I've used that tick all my boxes (subjectively of course) are Gnome 3 and macOS.
I think Gnome 3 especially does this extremely well. I flick to my upper right hot corner to expose my dock with my 5 apps - instant launch. If I want one of the other 15 I'm happy to type it in the resulting app search box. Done. I never understood why I would want to click and navigate for like 10 seconds (much less have to remember WHERE it is and WHY it is under a certain 'category') to launch one program from a Windows 95 style start menu. To each their own I guess.
EDIT: I should add a #4: Minimal customization. Gone are my days tweaking me DE exactly how I want it. While I do _some_ customization - it is very little (1 or 2 extensions)
