i always, always, always, treat the top and bottom mics separately from each other, because each has a different purpose for me
top mic usually ends up being compressed with a ratio between 2 and 4, attack around 25ms, pretty short release...gain reduction of maybe 4-6db. EQ is ??, but usually HP at 100-125hz, with a couple boosts using a "secret weapon" EQ plug that just kills on snares.
bottom mic gets compressed way harder, and gated to hell and back...10:1 ratio if not full-on limiting, fast attack and long-ish release, GR pretty much set to pancake. i also high pass the bottom track at around 150hz, maybe even low pass if it's too shrill sounding on the top end. all i want out of this mic is a solid SNAP to mix with the fuller bodied top track.
then i send both tracks to a single snare buss together, where the bottom is usually 6-9db lower than the top, and then finally they get Gclip'd together and sent to the snare verb
