In my experience the French Exchange is played by aggressive attacking players who just want to get some open lines and avoid the prepared lines of Black's French. Often the French is played by positional players who like semiclosed games and who don't like those open lines, even when they have equality.
Absolutely the contrary. Main line Winawer is basically a tactical mess, where white has a pawn more and great control on the dark squares, but many times he cannot move his knight from e2 (where it obstructs the f1 bishop) until move twenty-five, or so.
The exchange French is symmetrical dullness, excluding 4.c4, which is more active, but transposes to an IQP position which is quite easy for Black to handle.
Ummm, the Armenian...
Is there something new against white's continuation in Volokitin-Vaganian? If not, then the position does not appeal to me.
