Yep - even though you get to LB a bit more conveniently using Southern Trains - the delay there is a pain. On the other hand - coming home if I manage to run out the door on time - LB gets me home quicker (by a couple of minutes!!) if I can get to LB for the 18.06...and you normally get a seat vs no seat at Canada Water.

(I am obsessed with working out the quickest way home but it always varies depending on what time you hit each point!!)

But I guess this is a discussion that could run on and on and I've answered your original question so now I will shut up
