I own the Park CT5 and the X-Tools Pro Chain Riveter. I prefer the X-Tools one for a couple of useful features. It has an adjustable and locking barrel so you can set a stop for the pin. Keeps it from pushing right through if you don't want to completely remove the pin.
It also has a locking barrel on the screw itself so you can set it to stop a new pin at a specific depth.
