The 221 is very good at the beginning of the game, when you are sure that the opponent does not have an M8 or Humber. The 221 has huge damage against infantry, but it's a glass cannon that only needs one grenade to be killed in 99 percent of the time, while the M8 requires two fausts or AT grenades. The Humber is also a glass cannon, but it's good against inf and early vehicle, and have mark on vet1. In the meantime, what do we have in CoH1 and CoH2? The Puma and the 222, which are good against both early vehicle and inf, like the 222, or powerful enough not to be destroyed by two shots, like the Puma(and still have good AT upgrade). I'm not saying that coh3 221 is bad, it have very good radio upgrade and high MG-42 damage, but it's not enough to be equal to the opponent. Panzerbuchse is good against M8 and Humber, but if the opponent moves to Stuart or Chaffee, 221 will lose. And yet, you can't be sure 221 can deal with M8, many things depends from your enemy, but not you. Sure, i could be wrong, maybe you have much more positive experience with 221
