So as usual you'll likely never get a concensus. Because they both have strong points. That's why I wasn't to particular. There's a reason pro shops have both. I will say of all the things people have mentioned, dropping an engine and K member out the bottom is the only thing I can't do with a 4 post. And I think I could, minus the LCA's. Transmission, no problem. The jack pans solve the problem of doing wheel work. And if I got ingenious with straps I could pick a car up with the ramps on top, and back a trailer underneath it. Plus I didn't have to bust any concrete, and it plugged right into the 110vac wall outlet. Good luck with whatever you pick!
