If you are talking about a vehicle for shock purpose, you get luch, which has better performance then M20 and it is a decent sniper hunter also. Note that a unit can have multiple role and each role may have different target to compare.
again m20 is not luch, luch is a light tank, u are comparing luch to m20 while saying pak m8a1 are not comparable to stuka when they are both long range indirect fire platform
u are just another hypocrite on this site
