I like 19 D/H even over row 16. I find the legroom is fine for me (about 5" 10"). I find the tray tables in 16 to restrict the seat a little even though I fit fine. With 19 D/H if the person in 19E needs to get out they can go either way. I had 19H for HKG to DFW and found it ok.
I have 19H for my TATL flights in case my SWU does not clear.
