Tatsujin is a bit of an exception as its chips drums are some much more awesome than 99% of others.
City Hunter has a few good chip drums as well. It's a pity that NEC Avenue couldn't sort themselves out, every time I hear their attempt at drum sounds, vomit pours out of my ears.
Bugger me, you may be right about PC Genjin sample drums. Cutting out the other channels, there is a definite hiss behind the drum sounds that you'd get from a sample.
