The SPMBT and SPWW2 game engine should be practically identical, with the only exception of WW2 not using modern stuff like tandem HEAT and so on. Currently the SPWW2 is a lil' bit ahead, to be even with MBT once next MBT patch gets released by the developpers.
Compůarison with SPWAW is always tricky and relies much on personal taste. Me, i like MBT/WW2 series more, think it has better gameplay features and... 15 height levels and great map generator - need I say more?
