It's been a while since I've been on the A321. For an upcoming ATL - PHX flight, there are no aisle seats (my first choice especially for longer flights), but I can either grab 13F or 26E.
I know from past experience 26E has a ton of legroom and the added benefit of not being 26 BC (where people congregate), I don't think I've ever sat in 13F but I believe it is similar.
This is a morning flight (and business trip) so not overly concerned with the 'benefits' of C+ since I can expense out food and unlikely to have anything to drink other than a Diet Coke or similar
