I have the first one, and have had but given away one similar to the second. I honestly can't really recommend either. The first one is very small, and has pointy edges. That being said, it is machined well and spins well.

I don't really like the shape of the second. I find that there isn't a deep enough groove between the arms to get good flicks.
