Bigger wheels are much better. Try a 630 bike
after your 622 and feel the difference.
Or likewise try a 584 after the 622 and feel it
getting even worse.

Again, how big exactly are the 29 wheels? I ask
because in the MTB bike world aren't both 26
and 27.5 actually 584 or 650B?

29" is 622mm, the same as a 700c. 29" is just made to mount fat tires.

The difference between 584mm/650b and 27.5" is that the 27.5 frames are
made to mount wider tires,,, I think up to 3" wide? Plus still have
decent mud clearance on both sides (1/2" or so).
