I used a Stinger on my Yeti 575, but I've swapped to the Bionicon jobby on my newer Zesty. I find it works even better. A week in the Alps and the chain only dropped 3 times on to the small chainring in the rough stuff and never onto the BB (which happened occasionally with the Stinger). Doesn't have the problems with the roller seizing either (the Blackspire roller only has a bearing on one side, so used to find it dragged more and more in the gloop).
I find that, because the Bionicon holds the chain at a point that is further away from the chainset, there is less chain slap, due to the rearmost length of chain (between the chain guide and the r mech) being shorter. I run a shadow (non clutch) r mech and don't find it noisy etc.
I'm running the Bionicon with a set of XT cranks, 38T outer and 24T inner, plus a Blackspire C4 bash, which seems hard as nails.
