FWIW, I have had zero slippage with my cinch buckle.
To me that's probably the best reason why I favor the cinch buckles. Someone else posted awhile back about having to rely on a knot at the rings and not just the rings themselves. The piece of mind of not having to tie a knot puts the cinch buckles in the lead IMO.
That being said, I've had no slippage when I used a knot at the rings.
