the extended and open ended lug nuts are going to look stupid without you having a lot more going on with the car.
spline drive lugs will eventually break either the lug, or the lug sockets. have fun with that. (hint: do not buy.)

unless you literally never, ever use air. even so, spline drive lugs are ugly. and the key will break.
