I can vouch for MakeMKV as well.

I had so much frustration trying to rip Blu-Rays other ways. Did the free trial and got my whole library ripped pretty cleanly and easily. Eventually decided to buy the software so I wouldn't have to keep looking up and entering the trial key. There's not much higher of a commendation I can give than to say that I decided to give them $60 I didn't have to because it was good.
