I think that actually there are a few lines against the Budapest where White has all the fun and Black struggles in a "solid" but lifeless position. My favorite one is 3...Ng4 4.e3 Nxe5 5.Nh3. I'm not very impressed by Taylor's 5...g6 antidote to this. Various people have recommended 5...Ng6, but I think that then White can build up slowly with 6.g3, Bg2, O-O, Nc3, f4 and so on and so forth, and Black must just sit tight and wait for White's kingside expansion. As in many lines in the Budapest, Black has nothing good to do with his KB, and in this variation, exchanging it with Bb4+ Bd2; Bxd2+ Qxd2 significantly helps White's cause.
4.e4 may be good as well, but cost of that expansion is that Black seems to get more counterplay than in the various more conservative treatments.
As for the Fajarowicz, it's refuted by 4.a3.

In the hands of a strong player as Polugayevsky (or as matter of fact, Kiril Georgiev), space advantage in a position without any counterplay is like a Chinese water torture. Very often Black will be squeezed to death. Of course, White should be glad to get such a position - in most "regular" openings he can only dream about that. That explains why the Budapest is unpopular at high level. White has different ways of making Black passively suffer for many moves.
Right, and even if you manage to draw, you're exhausted going into the next round.
