You can probably just find some bottled versions of yfood and huel in a local supermarket for the same price as a sandwich and try them out.
I stand by huel having better nutritional value, and it’s plant based. But it’s also a bit grainy, if you are fussy about textures it’s maybe not for you (bear in mind making it at home from a powder has a much less desirable texture than the bottled stuff).
Basically - taste and texture a priority = yfood. Nutrition a priority = probably huel or huel black (depending on your nutrition goals I guess).
