Not a large poll but I didn't find anything better in a quick search on Google.Furthermore the sample is relatively small and my own sample is at least 100x smaller.
Second your desktop comment, Unity is unusable for me.
Yeah, it wasn't even Unity. I prefer i3 anyways. It's more that I like the bleeding edge (I need it for a lot of stuff), and I hate having to re-install every six months.
Nowadays I'm mostly with small, early stage companies in the Silicon Valley. From what I've seen in this environment, the OS of choice in production (cloud instances) is almost overwhelmingly Ubuntu.
On the desktop, however, I use Debian Testing instead. I am waiting for the day when I can use LXD on Debian out of the box.
If you're breaking your system every six months, that's probably because you're using the October releases instead of sticking to the April ones (which are usually the LTS ones and have fewer experimental packages).
My rule of thumb is to only set up October releases for playing around and getting a feel for what's coming down the pipe, and NEVER use them for production. Only the .04 ones.
Oh, wait, this is the MEAN stack age :)
