Depending on what camp you originate from within debates on macros, calories, etc. you may find meal-replacements to be useful or useless.
So long as a majority of your calories (and protein specifically) come from whole food sources which bring minerals, fats, or other nutrients to the table (whole eggs, chicken breasts, etc.), I don't see the harm in them.
That being said, I like to integrate the tastier protein powders into my liquid meals; I'll usually blend one scoop of Ultra Peptide (by Xtreme Formulations) with 2 cups of cottage cheese and pour it over 50g of whole shredded wheat. If it's bulking season you can add some peanut butter in there as well. Alternatively, you can play with the UP:CC ratio depending on your needs.
