The main drawback for some people is that MakeMKV does not compress anything.
Most people who make backups of Blu-ray fall into two camps. First are those who make uncompressed copies, either still in Blu-ray format, or in MKV format, and second, there are those who want much smaller files that take less room on their storage drives and will play in their portable devices.
So MakeMKV is not seen as an all purpose tool in the way that DVDFab is, and doesn’t fit the needs of the second group at all. At least, not by itself.
I keep MakeMKV in my toolbox as a second decryption tool. Like you I also have AnyDVD HD. I rarely make full sized MKV files, so I don’t need MakeMKV for that. To compress to fit 25gb discs, I use BD Rebuilder, which I find [B]vastly[/B] superior to CloneBD or DVDFab. To make smaller, compressed copies in MKV format, I use VidCoder.
So it is still possible, even in 2015, to use free tools for everything. MakeMKV is free while in beta. BD Rebuilder and VidCoder are superior free tools for compression and conversion to Blu-ray, MKV, DVD-video and MP4 formats.
But back to your original question…I heartily recommend MakeMKV to anyone who needs decryption of Blu-ray. It offers two different modes for ripping, so it is possible to use it to get full backups your movies, as well as MKV files. Philamber has pointed out the few downsides to using the program.
You can get new beta keys from the MakeMKV forum and continue using the program for free. You’ll need a new one about every month or so, and get them here: http://www.makemkv.com/forum2/viewtopic.php?f=5&t=1053
