I looked at both recently. Personally I decided that taking the fuel filter off every time I needed to check the Fuel Pressure would be a major PIA. I purchased this one off EBAY from TBIParts
I like the fact that I can check my fuel pressure without taking anything apart. I do have to get a 0-15 psi gauge instead of the 0 - 100 psi gauge on the fuel pressure tester that I use.
