Well to be honest/direct he didn't ask about SB Pro PE (which is the best tank sim ever, but modern warfare only)... He asked about WW2 battle Tanks and Steel Fury...
to answer your question...
WW2 battle tanks... buggy, simple, broken MP, fun sim light SP
action, no support from developers or community...
http://www.simhq.com/_land3/land_102a.htmlSteel Fury... few bugs but not many, No MP, more of a simulation then an action game, under rated great game IMO, no support what so ever by the developers, but the community has done well with it, unofficial patch, widescreen support fix, Steel Panzer mod with tons of great stuff...

If you want more of a WW2 tank simulation then Steel Fury with the unofficial patch and Steel Panzers mod. If you want MP, move along, nothing to see here.
