VS073 Manchester to Orlando

Hello all,
I`m flying out with my mate to Orlando on the 17th May out of Manchester on Virgin VS073 747-400. Our seat map has just become available (can't actually select any yet but read has to be 89 days etc) and we're booked in Premium Economy.
Just looking at the seat map there appears to be PE upstairs and downstairs. Can anyone suggest where is best to sit? I did ring Virgin Atlantic who said all of there 747's had now been upgraded , can anyone confirm this is correct as in the past I've read about the old style aircraft having PE upstairs and it being tacky?
Hope someone can help. Thank you.
