I am probably one of the few people in the recording universe who has never personally used an SM57 on snare. I have been present when they have been used, but have never used one myself.  However, I use the 835 on snare all the time.  It does just fine IMO.  When auditioning mics for live vocals I chose from 3 candidates: SM58, SM57, and the 835.  I chose the 835, so as I now have one around the house, it does double-duty for snare.  I found that the 835 and SM57 worked better for my voice, and the 835 sounds more similar to the 57 than it does the 58.  But the 835 has a crisper high end than either of the Shures.
