Logan, Wendell, what do you think of the 21:9 aspect ratio on monitors etc.?

Hey guys, I got my first 21:9 monitor (25inch LG) last week and am very happy with it!

I heard Logan say in a video about korean monitors that he used 29 inch on his secondary rig, now I wanted to ask what you guys think of the 21:9 aspect ratio on monitors etc.? What do you guys think this aspect ratio is good for and what do you use it for? Do you use them on your main rigs?

Cheers
