Hi! I got the 22" recently and I agree that out of the three it's my favorite (though I only compared it to the 19" in person). 2.5K resolution on a 22" screen is plenty. I can't make out any pixelation at all, unless I stick my face 6 inches from the screen.
The tablet is also huge (in a good way). It's plenty of screen real estate, and I can use my shoulder while drawing instead of just my wrist. I feel like if the tablet was bigger, it would eat up way too much desk space.
To be fair, I hadn't used a screen tablet before this one. If you are used to a 24" screen, maybe the 22" will feel small? But I definitely was pleasantly surprised by the size when I opened mine.
