I have only ever used the original 10 round rotary, and an HC3R. Both were a little troublesome with fail to feed issues the first couple times. Both had the same problems when brand new. When the bolt was back, and coming forward to pull a bullet out from the top of either mag, the bullet would go forward, and get caught on the feed lip which should direct it upwards as the bolt pulls it forwards. However, after a couple hundred rounds, both really smoothed out, and I have not had the same issues. But that could be just on MY 10/22.
I personally went with the HC3R over the Butler Creek simply because in person, side by side, the HC3R seemed to be of higher quality, and better design. It was also about $10 difference in price, which I felt was worth it at the time. I wouldn't mind trying out a BC if I could get one for less than MSRP at most local stores to me, but I'd rather divert that money towards stockpiling some ammo, or getting a pistol. But that's just me and my current situation.
