Really depends on what kind of beat is it

If you have an r&b beat (pads'n shit), It would be wise not to use too much percussion work. Again this depends on the tempo of the beat

I'm not a big fan of slow percussion work... It sounds boring.
To a hard hip hop beat, maybe some Eastcoast Jay-Z kinda stuff, It may give a nice feel to it, if you delay the hats a bit (Like move them to the right in the piano roll) So that it get's a feel of being unquantized and thereby more oldschool...
In beats there are more ambient or ballad kinda, I personally like having some banging drums... It depends a lot on your sound choice. Make sure the kick isn't too dry and make sure that the kick and the snare have an affair with eachother... more precisely they fit eachother. Then the percussion work comes. Again it really depends on how you want it to sound... I've always like more ethnic percussion. Like a bongo, tambourine etc.
Brief : In the end, it depends on your sound/sample choice, your panning and voluming (Like GP mentioned), and what you wanna do with it. And it's not always that the thing which makes the beat bang, is the kick and the snare... It's often the percussion, and cymbals, which gives that extra thing.
How would "That's my bitch" - Jay-Z, Kanye (Watch The Throne) sound without percussion work?
