Problems mentioned there are specifically about xf86-video-intel. Although I do
agree — it'd be cool if everyone contributed to a single driver.

I was just wondering alike, but about my local PC. So, just FTR, if anyone
would query the internet for the same question: upon research I didn't find
much difference between -ati and -modesetting. From the latest benchmarks I
found (April 2016) they seem to have comparable performance. Then I looked an
activity of both drivers, and found that -modesetting¹ has latest commit 3(!)
years ago, whilst -ati² just 4 days ago. So, for end-users: unless you see
problems, it's better to stick with -ati.
