Skimming the ingredients and descriptions for those, they seem to be intended as protein powder mixes for bodybuilders, not general meal replacements.
Soylent has 20g of protein per serving, and most of the products listed above are also in that 15-30g of protein range and share most of the same micronutrients, so functionally they're about equivalent. The only real differences between all these products are marketing, price, taste, "recommended" serving sizes, and small tweaks in nutrient ratios. Other than that, they're all pretty interchangeable.
This breaks down easily into per-meal replacements especially for the powder. Half a bag is half a day's needs, and so on.
That is literally the whole reason Soylent exists. As far as I know, it's the only product that works that way at that price point.
