I like a window with a view so if I’m not in front of the wing, I like to be as far back as possible. The very last row has a number of advantages – nobody behind to kick the seat; people face forwards so conversations will be directed away from you – most likely row to have a centre seat left free. On the downside, on one flight there were smells from the loo; sometimes the seat doesn’t recline properly (no bother for me as a non-sleeper non-recliner in economy); and occasionally the last row doesn’t get a proper window which is annoying. Depending on the flight, you might be last in the catering queue, but sometimes you are first. I have never found people queuing for the loos to be bothersome, but as I said, I am a non-sleeper.
