I've been using XFCE for about 3 or 4 years, and I really can't complain, it simply doesn't get in my way, it doesn't force me to relearn the UI, it even works with my old 800mhz EeePC, and the theme used with Xubuntu doesn't look as ancient as people say.

I remember trying Mate in the past, but I also remember I had issues running GTK3 software and I didn't feel motivated enough to dig for a solution. What I wanted was a hassle-free DE, and XFCE was the one for me.

I've been on XFCE for over 10 years. Old style menu, never gets in my way, runs GTK and QT apps, easy to exetend, four monitors, etc. So simple and stable. I've avoided so much yak-shaving that other desktop Linux users I know have been stuck in, more than once.

Cheers to XFCE team!!

The last time I tried XFCE I found that HiDPI support was pretty much absent, has this improved?

I use XFCE on a 4k UHD 40" samsung TV at 3840 × 2160 for my work machine. It seems to work just fine.

I was just trying Xubuntu. There's a setting to switch to 2x scale. Didn't seem to affect It apps. The window decorations stayed small, but there's a theme with larger ones. The cursor stayed small but can be adjusted.

Replying since I can't edit: it should read "didn't affect Qt apps".

It's not great, even in 4.13. Price I pay for stable is that "new" features take a while.

Yeh I love xfce as well. LXDE or XFCE and I am a happy camper. I even use them on powerful computers as well.
