Personally I love it and now this aspect ratio is my prefered choice when it comes to monitors.
Sure it can be a bit of a bother when games don't support it properly out of the box but most of the time there is a workaround to remove the black bars.
'sadly sometimes even new games do that crap..'
Switched to this monitor in 2019 and it was weird at first but I got used to it completely by now and actually the 'normal' aspect ratios feel weird.
I did look at some new monitors recently cause I was curious what are the current options with this resolution but not much actually and I would rather not step up to 3440x1440 cause thats a bit too difficult to drive with my usual budget-entry mid range hardware.
That being said I do not play competitive games so I have no idea how this would work in those games but for single player its great imo.
