I'm slightly certain that Rows 10-11 have greater pitch. Row 10 is probably non-reclining, but that may only be the window seats. Also, I usually hate the exit row window seats as they don't have a full armrest along the sidewall. If 10 C/D reclines, then that would be fine. 11C/D you have the "issue" with a non-EMS seat behind you, so if you recline, you might annoy that person and they may kick you. Same in row 5 (though this is generally less an issue on B6 than other airlines because even non-EMS seats have decent legroom). Personally, I definitely don't like the bulkhead -- can't stretch out your legs. If you're shorter than maybe 5'5" it's probably fine though. But if you have wide hips and/or meaty thighs, the tray tables are in the armrests so you might feel somewhat restricted.

In sum rows 2-4 would be my preference.
