I'm not too sure which has more power....but FI is excellent in throttle control/response.

throttle control/response is NOT equal to power/torque. If u have a powerful bike, throttle response makes hellotof difference! otherwise, (in case of 250r) i dun c any difference. Maintenance is a separate issue...
