IMHO 1A is a non favourable seat, not as bad with the new lieflats as with the old config, but the curvature of the wall makes it a little cramped actually. Remember that with the new seats the person in front of you never invades your space while reclining so bulkhead is not as important spacewise as it used to be (with the old seats row 1 was a no-brainer).
If you are not a window-guy any of the middle seats are preferrable as you will have aisle access and still no one to climb over you.
If you travel two persons and want a little privacy 6GH is actually a good choice as you will have the storage locker to the left of you and no one will watch what you guys are doing in your little private corner. Downside is carts might bump in to the G seat at times (breakfast serving).
