GNOME has been doing some really cool stuff as of late (
http://www.omgubuntu.co.uk/2017/03/top-features-in-gnome-3-2...). I'm still using Cinnamon, because I still like the look a bit more, but it's getting harder to ignore all of the excellent features GNOME provides, including:
- Drive support for file manager
- Gmail/Outlook support for GNOME accounts and built-in calendars
- Working Wayland implementation
I'm holding out at the moment, as it's missing one feature from Cinnamon that I really like (the ability to launch and control any audio player from the sound icon in the tray), but when Fedora 26 launches I may finally have to switch over.
I hope that Canonical shifting back to GNOME will further its development under Wayland and not spend a crapload of time doing more work for Mir.
