@Olde Navy this will be one of the best decisions you'll make in your tiling career.
The max handle in a sense does away with the need for the klick klock. The klick klock design makes it easier to see your marks on the tile, bug the Max is an upgrade of the pushing ethos.
It does have the greatest breaking strength by some margin.
The pull handles are better suited for speed on say a commercial job with dozens of repetitive cuts. I've got a wrist injury so am currently using push handles as they are far more comfortable. You can buy the other handle types for each machine if you feel the need.
The 3C3M is the machine I would recommend for general day to day with
standard formats and as
@impish has said you don't need a case.
You'll find yourself wishing you had switched from Rubi years ago
