In my opinion gates can certainly be very useful. I use them quite often. However, if you have too much hi hat bleed I still maintain that a gate can be counterproductive to that problem. It's really a physics issue. Too much bleed with a gated snare can often look like this...... chick..chick..CHICK..chick The CHICK is where the gate opened. Often times compression will exaggerate that even more, depending on the sound and EQ of both the hat and/or the snare. When I get too much hat bleed I usually will start leaning a little heavier on the bottom snare mic and poosibly even blending a sample in with the bottom snare mic. I also start to lean a little heavier on the room mics and/or the overhead mics. I really like the idea of trying to make the hat become a part of the snare sound. I do that all the time, bleed or no. But too much hat means that sometimes you have to compromise your snare sound to use the top mic the way you normally would.
As far as John Bonham goes.... Of course almost every drummer worships him. They all love them sound. Most drummers however don't want that sound on THEIR kit. Led Zeppelin left a lot of space in their songs for a sound like that and it became a part of their "signature" sound. It is a VERY different sound then 99% of what people do now adays. It's not because they can't get that sound, but because it isn't the right sound for them. Which also means it may not be the right technique to use either. If you have an incredible sounding room, awesome mic and prea combos, a really well tuned kit, and a drummer that really knows how to control his dynamics to maximize the efficiency of the room, method of recording, and equipment used, a 2 or 3 mic approach can do a great job with ROCK drums. If you are missing parts of that chain though, you may seriously regret it come mix down. You won't get that Danny Kerry sound with 3 mics. My biggest complaint with not close micing is that I like the chunky beefy tom sound on a lot of rock drum mixes. That just does not happen very well with a 2 or 3 mic approach unless you have a lot of other things going for you.
