I can vouch for SBR. I've used it on several classes and it performs really well.
Like always, there is always a risk with using a (rotation)bot on your account, and there is no guarantee Blizzard won't detect you and ban your account.
However I'm not aware of any ban waves against SBR like what HB/PQR/PE had, but who knows what next week/month/year brings. If you want to be 100% sure not to lose your account, you shouldn't bot on it
Another big plus with SBR is that it runs on Mac/OSx as well so there is no need for bootcamp etc if you want to play on a mac.
