There are variations on both, I'd highly suggest a VTEC DOHC enabled car featuring either a B16/B18c, H22 or K series engines

These engines are smooth, potent, and above all just fun. Their featured models also generally sport the highest technologies available from Honda at that given time, so they are really great cars.

The SOHC VTEC designs usually showcase an improved torque band over the same rev range, or better gas mileage in the same rev range as their non-VTEC counterparts.

BUT this all really depends on what you want in a car, if you give us a better description of what you're looking for we will probably be able to point you in the right direction, whether the car be a Honda or not.
