While the legroom is similar to 19A, be aware that the window isn’t really aligned so you’ll have no real view outside. If that doesn’t bother you, great. I’m similar in that I get claustrophobic, but it’s amplified even more when I have no reference point to the outside so while I like 19A/F on the 757, I’m not a big fan of 13 on the A321. On AA’s their seats are set back farther so you still get a window. Again, if this doesn’t bother you then it’s still plenty of room to get up without interfering with anyone else.
