Panzerstorm in my opinion is one of the best Battlefield maps to have surfaced in recent years.
it has everything: Lots of room to maneuver and flank, some great hidden avenues of approach for infantry as well as tanks and lots of sneaky points to set up deadly ambushes
And finally, using the transport vehicles, towing cannons makes complete sense in this map and actually serve a purpose.
it just seems to me, that everything comes together exactly as it should on this map, you've got your infantry attacking the flag and taking out enemy fighters in the hangars and buildings and then you have the armor flanking and covering infantry and engaging other armor. you've got your airforce up above scouting and providing support to friendlies below.
the sense of scale is pretty amazing and advancing through the map just feels like you're really at war.
is it a tank map? an infantry map? a bit of both actually, focused equally on both. and that's why i think it's so good.
(but then again this is only my opinion)
