Try to be more respectful of other people's opinions, if you want them to value yours, Telestu. My own opinion is that white has a definite plus in the Nc3 lines and so doesn't need theory so much. It's all pretty straightforward. Whereas, in the Advance, white is trying to erect a rigid pawn structure and the smallest error brings problems well down the line, after black gets a dynamic advantage. The theory is subtler and probably more important. In other words, it's possible to wing it in the Classical but not in the Advance.
IMO 3.Nc3 is the best test, but unfortunately also the most difficult.
The winawar in particular is a huge headache and a huge amount of theory too. Black can also choose 3...Nf6 which is its own big world of theory.
If you play 3.Nc3 and immediately go for sidelines, then sure, you can avoid a lot, but I think it's very misleading to say you can just go with 3.Nc3, play natural moves and not worry about theory. It's not my opinion that 3.Nc3 has more theory attached to it than any other variation, it's a fact!
Everybody that plays White against the French is always avoiding the dreaded Winawer (1.e4 e6 2,d4 d5 3.Nc3 Bb4), In my days as a professional gunslinger we knew it as the Win-A-War. The delusional way around it is 3.Nd2, which is known as the Tarrasch. But better known to gunslingers as the TRASH.
I believe the OP is avoiding the Win-A-War by playing 1.e4 e6 2.d4 d5 3.e5
