I want to buy the full 6 movie saga set (the 7th won't be out for a while, I guess) and I have searched and learned that each blue ray set has more or less important differences. For example, some come in 6 disks, others in 9 disks, some scenes were deleted/added, other scenes were CGI remade/modified, differences in quality of sound and image quality, etc...

Which is the best blue ray full saga set to buy?
Thanks in advance.
