I was focusing on 1v1 maps first, but i also think that Hürtgen Forest is terrible
Moscow outskirts is also a lot harder from top than from bottom (that top cutoff on the left...). Vaux farmlands is OK, its just ten times easier with allies than with axis (only 2v2 map where i think cons spam into t34 spam is not only viable, but almost unbeatable because of the size of the map).
"Honestly I don't find those maps being too unbalanced, it could be that you have simply a special preference for each map."
Consider writing down your wins/losses from each sides. I also watch a ton of games from pro players (on live stream or ingame live games), and i can tell you that the difference between the winrates in Semoskiy top are insanely low, compared to bottom.
There were a countless times when i saw a game and i was like "hmm, Siberian/Luvnest/etc plays axis from semo winter top, im curious how he will win from this side, i will learn a lot from this game!" and then, "well, he lost."
