Only thing WT really has is the massive variety of planes and country represtentation.
AND
The system that closely matches them up: A majority of the planes in WT would end up as hanger queens here.
You mean false matchups? Like as soon as you get to Fw190s you get mythic planes ruling the tier and owning the skies? You mean paper designs that never saw the light of day? You mean artificialy fluffing aircraft lines and padding them across multiple tiers where they are outmatched JUST to pad the planeset to make it look like there's something there? When there's no difference AT ALL in how the play across 3 tiers of ranks?
You mean how you can't get to 1944 without fantasy jets and F8F bearcats owning the entire skies?
You mean how there is no middle game and you lose any pretense at balance past tier 1?
You mean how they give one nation a plane, then pad another nation with the same plane, but move it up a tier for no reason?
You cannot make any claims that WT has a more fleshed out planeset or any kind of balance -- the utter lack of balance and horrific imbalance and fake made-up flight models to pad fantasy planesets rammed into a line up JUST to make it seem like there's some kind of equivelant planes there even though there never would have been in reality is what has driven so many serious flight sim players from the game.
WT is 90% steer poop. Pure and simple. They do it that way intentionally to pad out their grind-fest game because they make MONEY off of people unlocking upgrades for planes (which just makes them 100% pure fantasy performance planes anyways, regardless of which tier they are mis-placed in).
If you even pretend that there's any kind of better representation of nations I dare you to look at Japanese and the newly-included Italian lineups. Puh-leeze. Get real.
