If you want big huge drums, don't gate anything. The RHCP's and STP get their drum sounds by having pro gear in pro studios with pro engineers and producers at the helm.
If you're interested, the guy who mixes the RHCPs live is Dave Rat--he has an excellent blog about touring with them (and others) that you can find HERE. He's just setting out for a month mixing Soundgarden then straight into a couple of years of world tour with the RHCP. The blog mixes gossip about touring with some very useful tech stuff--it's worth searching back into the older posts of touring with the RHCP for some good sound nerdery about his techniques.
As for gates, they can be useful, getting more so the more mics you use on your drum kit. However, they have to be used sparingly otherwise I agree they start to sound artificial real fast. However, just a touch carefully set can cure bleed between sources and clean things up a bit.
