No black has lost 2 tempi, e7-e6-e5 loses only 1 tempo, so it must have been something silly like Nb8-c6-b8.
Queen's Gambit is far stronger than Vienna Gambit: in Queen's Gambit black cannot hold on to the pawn, in the Vienna Gambit he can with 3...exf4 and 4...g5. Also 3 f4 weakens the diagonal g1-a7. Vienna Gambit is playable of course - white can afford a lot - but it is not in the same league as Queen's Gambit in the sense that it is unlikely to show up in say a World Championship Match.
