I didn't find the 19 or 22 attractive at first, but I ended up reconsidering and now have a small black 19, small 21s light pink 19, and a small white 22. I admit that I enjoy the 19 so much more than I expected as it's so versatile, comfortable, and is a good style combination of classy and edgy. The 22 is great too for being so effortless whenever I dress down in sweatshirts/tees and super casual gear, but I definitely prefer the 19's look overall based on my personal style. I also have old medium boys and still love them without any thoughts of parting from them, but in the last few years I do reach for my 19's more than any bag I have (including CFs). I can imagine the 22 eventually phasing out, however the 19 may be lingering for a while as it's also iconic in its own way as Karl's last major design.
