I'd second the idea that one good wood and one good metal...probably maple and steel...would do a great job for your Strat/Les Paul comparison. If you just want one drum, though, I'd probably go with a maple drum...although a brass drum will often give you a sort of compromise between a maple and steel drum...brighter than the wood, but not quite as edgy as the steel.
I think it's a very good idea to have a few drums around. Especially since you say the main problem you encounter with many of the bands you record is inadequate gear...chances are those drummers aren't using the drums they use because they're what they want for "their sound", it's because it's all they can afford.
