Comparing all the dxc4 lines in the QG with the Petroff of course is very much in favour of the first. But the fair comparison is NID/MNb2 with Petroff. For instance, in some off Inn2's formerly recommended 4.f3 lines drawing rates are even higher than after 2...Nf6 ....

Desparation even grows bigger. Of course 4.Qc2 is good, but then Black is the attacking player. So tell me how to attack the NID (don't tell me how to play for a minute edgame edge; not interested) and I am converted.
which drawing line bothers you after nimzo 4. f3 ?
There is plenty of interesting play after 4... c5 and 4... d5 / 8. dxc5 main line. 4. f3 0-0! looks trickier though.. perhaps you might say 4. f3 is better suited for OTB than correspondence chess since White seems to get easy play OTB, but computers often misevaluate 4. f3 positions, so i think 4. f3 is also good for correspondence chess.
it sure looks like the stock of 1. d4 is rising since the stars of Topalov, Aronian, Radjabov, and to a lesser extent, Jobava are shining now..
@Willempie: the problem with the Petroff is the lack of pawn play in critical lines, so White is relying on piece play, which demands great accuracy to gain advantage. therefore more of a need for White to know exact theory. But agree it is not possible to attack in every line, in QG/Slavs and Samisch KID/Benoni for example, usually am more concerned about suffocating Black than attacking his king. I think 1. e4 is a much better move if White is hell-bent on the king on g8!
