If it handles the head bolts, I would say keep the 1/4 inch..
Far easier to use on small stuff..
I wish I had a 1/4 drive , my 3/8 Williams clicker, only goes to a low of 15 ft lbs , but I dial it under.. not sure if accurate ?
Non ratchet 3/8 get in everywhere, even Harley base nuts and head bolts, which usually get done by feel with a starter wrench, as 90 percent of the guys don't have a torque wrench that gets in there.
