RE20s, 421s, U47FETs, ribbon mics, etc., all can work quite well. Even old mics like the EV RE11 can sound great with the right cabinet in the right context (nails the Grateful Dead Europe '72 tone in front of a JBL 15" powered by a Fender style head). I have a copy of the U47FET made by Beesneez (T3) which is fantastic. In a studio, you could put up a dynamic, a condenser, and a ribbon and blend them all.
