Due to professional reasons I was always in the Redhat camp: Red Hat Linux/Gnome from 1996, then RHEL/Gnome from around 2004 then Centos at the server level and Fedora KDE on the desktop from around 2007. I was also an early adopter of VMware Workstation which was a revelation when it came out (still is despite the Broadcom crap).
Prior to that (from 1982 till 1996) it was Unix with no GUI, just the warm embrace of a CLI inside telnet/rsh/ssh (which obviously still pursuits to this day even with Linux although I sometimes use the BlueFish editor and not "vi")
And none of this Perl or Python crap... you will have to remove KSH from my cold, dead hands!!!!
I stuck with Fedora KDE as a desktop until I retired in 2019 (but I still program C/C++/KSH four to six hours a day, mainly in winter, because I just love it!!!) and went on a journey trying basically every Linux DE available (even fluxbox with tint2)
I find the menu metaphor very unproductive (too many key clicks) so I discovered Zorin and its mobile "skin".
Some DE's were kinda similar but fell down in many other areas, IMHO. Zorin is very easy to configure...it doesn't throw up lots of configuration "stuff" that gets in the way or is fiddly. It takes literally a minute from a fresh install to get the DE setup.
So now I have my main app icons on the task bar at the top (you can pack in 30+ apps with large icons there) and you are one click away from a full screen secondary panel with the rest of your apps (30 apps per secondary panel, you can scroll through any number of secondary panels).
I group my most used apps on the task bar by function (file browser, email, office apps, web browsers, network connectivity, programming tools, audio tools) and then alphabetically on the secondary panel.
I don't need more than one secondary panel...so for 30 apps I am one click away from the app running and for the other ~30, just two clicks.
Zorin is based on Ubuntu so package management was totally different from Redhat but for my retirement needs I find it better then Redhat as it has better support for say audio packages than Redhat.
But I did love KDE, it has lots of configurabiity that a professional might need plus it's sleek and modern. Many people like stuff like LXDE or MATE or .. but when you look at them, stuff like the icons and the general look and feel seem like they are from the 1990's (which they probably are!!!!).
And of course, with Linux you can use whatever apps you want. So I remove almost every app from Zorin (or any other Linux I might have used) and install my own list of "best of breed" apps like Dolphin, KRDC, Bluefish, Thunderbird, mHwave edit , DIA, K3b, mpv, vidcutter etc. I also use wine for Windows utilities I have come to love like Winscp, Putty **** and some audio tools like Spek. I tend to prefer utilities with a single focus rather than the "kitchen sink" type.
Why use a menu system?....surely you know what apps you have, what they do and what icon is associated with them so why not go "flat". It works for me but maybe not for you.

**** yes putty is available natively on Linux but I find the Windows version better.
