I agree that after the tracking is the best method.
Once it's on tape/disc you cannot change it. While you might have recorded the performance of a lifetime, you might be stuck with unforseen problems because of wrong settings.
But... this implies that you have sufficient tracks available to record the drums on. Gating in postproduction when you recorded on only 2 tracks is a living nightmare.
My opinion: record dry, using only a little bit of eq, maybe some compression (if you do not have enough free compressors at mixdown) or limiting.
A typical recording scheme without having a 24 track studio and 100 bank loans could look like this:
Record the drums on 6 tracks
T1: Bass Drum, T2 Snare, T3+4 toms in stereo submix, T5+6 overheads + HH.
Afterwards you can gate out all the unwanted spill in a computer editor like e.g. Wavelab. Gating these things out on a computer is quite easy, as you don't even need a gate. Just look at the waveforms and "silence" the unwanted parts in e.g. the overhead tracks.
Just a suggestion.
