To Upper Deck or not to Upper Deck?

I think I've seen some discussion of this before, but I've forgotten what the general consensus was. I see differing reviews leaving me confused.
For an eastbound sleeper flight, is it worth going for the Upper Deck on a 744?
Negative comments I've seen:
It was too hot.
You have to walk through a PE cabin.
Rather bright reflective cabin separator.
Ceiling too low.
Positive comments:
Very quiet, i.e. good for light sleepers. (Is it really not that quiet downstairs?)
Almost dedicated FA as small cabin.
I've never flown the upper deck before and I would like to know if I should grab the opportunity whilst I can.
Thanks in advance for any advice.
