I looked at both in person and both are well made but I went with the backyard buddy for these reasons.
- I feel the column over post design is superior to a c-channel type design. Not such a big deal if you plan to bolt the lift down, but on a roll around definately.
- The BB has a superior lock design, notches cut into the posts and out in the open and easy to verify there integrity. The rotary has internal locks that are adjustable (with a large nut on top) and very hard to see visually.
- The ramps were 2 pieces of c-channel welded to a piece of plate, the rotary ones were formed.
You cannot go wrong with either choice but with the money being so close I feel the BB is a better manufactured and engineered piece.
