I think some of these rankings are such a joke and biased.
Of course they’re going to have some degree of bias, they’re human opinions. They’re inherently bias by nature. Same as your opinions here…and mine, of course. That doesn’t preclude that the points you made lack validity, but they are written as absolutes and that can be confusing. For instance;
The best meal replacement shake for weight loss is the one that keeps you full while preventing you from exceeding your daily caloric intake goal.
The best, the worst, the whatever-est are all subjective absolutes, which is a contradiction in terms. But that’s one of many flaws in language. Maybe something like,
An effective meal replacement shake for weight loss would help to prevent you from exceeding your D.C.I.G. by keeping you satisfied until your next meal.
After all, nothing can actually prevent you from doing practically anything you want to do. Except maybe death, and even that isn’t always the case…but I digress. lol. 
That being said, just because you’re losing weight, it doesn’t mean that you’re actually getting the necessary nutrients your body needs on a daily basis.
Sort of true, however, how do you equate losing weight with getting or not getting nutrients? One doesn’t necessarily depend on the other. I lose weight every time I get undressed and that had nothing to do with food at all. Silly as that may sound, it’s still true. Ideally, we want to lose fat, not just weight. Muscles and bones have weight, as do our organs, but we don’t want to lose them [unnecessarily] do we? Of course not. But again, faulty language is to blame.
The better question is, which is the best nutritionally complete meal replacement shake?
Better, yes… The ideal question to ask would probably have been, “Which is the most nutritionally complete meal-replacement product available today?”
Any meal replacement shake can help you lose weight if you consume it properly.
What if you consume it improperly?? Can it still help me? Of course it can. If you consume much less than is recommended, and consume nothing else, you will probably lose weight.
I hope I made my point clear. Be well!
