IMO, the biggest issue with using dissimilar metals is KNOWING when the plug is "tight" enough. Generally, the plug is tight enough just about 1/8 to 1/4 of a turn past the point where it stops leaking. No more. Using teflon tape for sealing is fine but it can facilitate tightening the plug too much. Remember, pipe threads are tapered and they exert a lot of force on the threads/hole/tank with very little effort and they are easily damaged, especially if you use a large wrench for the initial torque. If the used/reused plug leaks, just buy a new one (whatever material your choose) and don't keep tightening it.
