You'd have to be quite tall to have smashed knees in any proper PE. However bulkhead seats often have the problem of allowing plenty of "kneeroom" but limited "legroom" since you have a wall instead of a seat with space underneath it. I can't recall whether this is an issue on VS' 333.
The last row is a good choice, although frankly there's not going to be much of a difference no matter which seat you choose.
