Many people have different problems with different programs when others dont. A lot of the time it comes down to not knowing how to use it properly or something wrong with their systems.
Another reason more errors are maybe reported with CloneDVD 2 is probably because more people are using it! Its a percentage thing.
Oh, and yes I have use DVDFab before as well! But I do honestly find CloneDVD 2 to be better.
