Oops my mistake, I did of course mean to say depending on the circumstances.
My only real problems with SB have been, as you say, stand 1 LGW and at some of the smaller (often newer) stations like OVD, PMO, NAP, LCG, RAK etc Gatwick isn't really set up all that well for group-by-group boarding though - a move to BFS-like pens would make things a lot more ordered. From what I hear, though, Menzies are being very strict about boarding by groups so I suppose that's a good thing.
