If you try to rip an UHD blu ray..you need a special reader.
It doesn't sound like the OP is doing UHD but this is a very important note. I bought an extra.
I'm another MakeMKV fan. It is free to try and pretty straight forward. There are 2 problems you should be aware of:
1) Some movies use obfuscation as an annoying form of copy protection. So you put the disc in and instead of there being the movie there are what look like hundreds and you have to figure out the correct one to rip. I usually would just do a search to see which .mpls file to rip. I think (and hope others can elaborate) that having Java installed may take care of this. There is some software (maybe AnyDVD??) that will tell you which file is correct.
2) Similarly if you are going to rip TV shows they may not be in the correct order. You need to confirm the order and enter the season and episode tags then let MC lookup the info. I also use MC to rename the files to include the season and episode numbers. Then if for some horrible reason I ever need to re-import the files it will be easy.
----My way to figure out the episode order is probably not the best but it works. I put the disc in a regular stand-alone player and go through the disc and take a pic of the first scene of every episode.
All that said most movies will go pretty quick.
