Having a little time under the hood, I think I like MakeMKV a tad bit better, it's a little more developed and lets you select what you'd like to rip such as movie only. BluRay Decrypter is a little more about just copying all of the disc. Great to see free solutions for this stuff finally.
I'm very impressed with how sophisticated Handbrake has become. I frowned when I first found out the author removed XVID support, but the quality it gives is a lot better. I'll put it this way, once I got my first HD rip in the same resolution as the original with great quality considering the filesize, it made this man look at his XVID collection with a little less um, excitement. This kinda blows them away.
Best part is Handbrake builds are made for OS X, Windows and some Linux distros.
