Agreed. My preferences on the 346 would be in order of priotiry:
1. Row 1 window (easy to get in or out since - your seat doesn't disappear under the one in front of you when fully extended)
2. Row 1 aisle on the sides
3. Row 1 middle aisle seats (they are closer to the toiletsand some times other passengers will annoyingly queue in your leg space)
4. Any other aisle seat
5. Any window seat.
