it all depends on your budget for a car. I myself use my HPI Pro 4 for both drift and grip racing but thats the higher end of the spectrum considering i bought just the chassis for $300 on the other end you have the hpi sprint which is $199 RTR with a battery and everything. in the SG movies they say at the end they are using a HPI pro 3, a tamiya TT-01, Yokomo drift kit, tamiya TL-01, and Tamiya TA04 they are all good kits i would prefer shaft drive over belt for the simple fact of less matience and less chance of a pebble ending your day
