It doesn't matter, dammit.
I've been a Linux-at-home user for 9 months now and it was a stressful time for two weeks (serious swearing) then a bit stressful (mild swearing) for two weeks; then it was fine. I used MS-DOS then Windows for 25 years and I haven't touched Windows since last November; I don't have it anymore except on the old spinning rust disk in a bag in my desk drawer. (SSD all the way now). I've tried MATE and Cinnamon and XFCE and a couple of weird lightweight ones and I've settled on MATE. Whatever you choose will work for you, because that's the reason you choose it - duh.
I don't startup my newish laptop, or desktop, or netbook, or 8 year old laptop (yes, it's great, with PATA SSD) so that I can admire MATE's system panel or the way it presents notifications. I startup my computer so I can run a browser, or an e-mail client or GIMP or splice audio files or play some music. I did spend some time setting up my pop-out panels and loading them with drawers and the drawers with apps and folder locations etc. - but then I started using my computer to do work. (Also, the great thing is that I can migrate/clone my MATE desktop environment over to another computer).
As for the Windows fanbois talking about 'fragmentation'; it's 'choice' and it's free :) I install Thunderbird or the latest GIMP from the same source whatever DE is used. If for some strange reason, I want to try Cinnamon again (I didn't like it), I can load it up and start in Cinnamon (Linix startup gives you that choice at a button click) and it still runs the same installed programs.
