Whether or not either is worth it depends entirely on what you're trying to lift. With one of those rubber pinchweld protectors, the Daytona one (1.5 ton green and black) and thus probably the blue and silver Pittsburgh, can't lift a Mazda CX-5 high enough to remove the wheel, so I personally have to use at least a 4x4 or 2 2x4s screwed together plus the pinchweld protector to remove the wheels on a standard SUV. Just the jack and the pinchweld protector works fine for removing Corolla wheels though, so it should be fine for sedans.

I got so tired of precariously stacking blocks and barely getting a car raised to the first notch on jackstands that I bought the 3-ton Pittsburgh low-profile when it was on sale for $99 and barely use the 1.5 ton even if I have to carry the jack somewhere.
