Take a look at Me163 statistics over the last few tours if you want to be bludgeoned by fact.
The masses will fly the easiest aircrafts that will maximize kills. Is that the "best product"? No, it's the easiest product. This tour, the P51D has ~12,500 Kills. The Ta152 has 1,400 kills. Last tour the P51D had 10 times as many kills. You argue the Ta152 is a better aircraft and I agree, but why don't the masses 'realize' this? I'm sure mostly everybody has flown a Ta152 at least once to see what all the fuss was about. They probably realized quickly that the plane is unbalanced, can't roll, goes into nasty tail spins, has an incredibly unstable gun platform making it difficult to line up a shot and even when they do get the guns lined up, the pesky ballistics make it near impossible to even connect. They then go back to their comfort zone planes which are the most popular rides in the game. They'd rather fly the easy stuff than learn the hard stuff and suck for a while, only to be better in the end. That's the way I have observed it and the stats don't lie.
I don't think I've ever flown the 152. I may have I suppose, by accident maybe? It has nothing to do with the flight model, ballistics, how hard it is, yada, yada, yada. I didn't even know it existed prior to playing this game. Now, knowing that it exists, I still have not had my interest piqued by it. I don't fly it because (like the other german planes) it's goofy-lookin'. I've never realized there was any "fuss" about the 152. Now, realizing I may have missed something exciting, I still have no interest in it.
I have flown the 163 and 262 a few times. Not too much, but some. My kill stats in those two planes have nothing to do with my squad affiliation. I've not found the 163 to be difficult to get kills in.
I fly the airplane that was my favorite as a kid, and still continues to be today, mainly due to its looks. Performance is a vastly less-important factor to me. As a youngster, we never even dreamed of internet, or internet flight combat simulators. Choosing my favorite plane had nothing to do with how easy it would be for me to get kills in in the MA.
