I'm 6'2" and prefer the bulkhead on the 738. It has a nice cut-out and lots of room. Plus you don't have to worry about someone reclining into you.
My last flight on a 738 in E+ was SFO-ORD and I had a bulkhead window seat. There was plenty of room for me to get up and get to the isle without bothering the other two in the row or asking them to move.
