I bought a LG 34CB88-P Black 34 ultra wide a few years ago. It is the business version of the ultra wide but with 75Hz and freesync support it is good for gaming. I cannot complain for the price i paid.
How is it compared to OLED? It's a Nano IPS display so it's top of the line for IPS technology. But OLED is in a different league, and I also have a 55" OLED TV. A 21:9 or 32:9 that has an equivalent height to a 27" display at 1440 would be ideal for me. But not sure I want to invest in one now or wait for what LG comes up with in a couple years.
Right now my monitor is a 16:9 27" professional 4k LG display without HDR for color accurate work.
I still don't understand how they can make a 43" 4k tv for less than $200 but then charge $700 for a 34" tv that is only a widescreen because they've cut off 700 pixels from the bottom of the screen. It doesn't even have as many pixels across. Yes the LG is 75 hz and has FreeSync, but they couldn't add that for $500 more? Which would be better a 43" 4k 75 hz FreeSync monitor or this LG?
