I thought you were debating which one to purchase...
I have one like second one as a kit in a plastic case. I've used it several times and it's worked well.
It also takes less space to use it. IIRC the first time I used it was to replace a vacuum pump on a 1996 7.3 Powerstroke. I used the puller on the pulley while the pump was still bolted to the engine. I don't think I could have done that with the two arm style...
