I use the one with the plastic head because it looks less cheap, but both keys are master keys. This is the first car I've had where there hasn't been a valet key. I was sure there should have been three keys (two masters, one valet) but no.
I used to have a VW with a switchblade key. Very cool key, but bulky because the remote is in there as well. Fairly expensive, but like almost anything else you can buy them cheap on ebay.
