better as in not needing separate power supplies and cases to have reasonable storage options. better is not needing to buy a new machine (I know, not confirmed but they never aren't offering) to upgrade components. better is having a user upgradeable storage (the ssd is not user upgradable even with tricks according to some).

While it certainly is an interesting case, stylish for some, its pure form over function. They have essentially made a Mac Pro Mini / Mac Pro iPad ... as in what you bought it what your stuck with. Want to upgrade to a new processor or newer video card, well buy a newer machine.
