You're right. It's the sound and the player, not the brand of drums/cymbals. I'd much rather hear/see those street drummers with their home depot buckets and broken cymbals playing their hearts out, than a guy with the "perfect" drum kit playing only 2/4 backbeats.The one run there is in drum set-land: there are no rules. You can do whatever you want gear-wise. Playing the drums with others dictates certain rules, but that's a whole 'nother discussion. I remember David Garibaldi (of Tower of Power) back in the 70s playing a kit made up of different manufacturers, but they were all the same color, but his groove and playing over-shadowed all that and it was a great show. That's all that matters.
