Great, but for lots of people that are lactose intolerant or allergic, it can be good enough. Some are better than others. I am not fond of Daiya, and prefer Violife. You also want to use less of it, and choose or modify recipes accordingly.

Most of the grocery store available ones are more appropriate for ingredient substitution. Cultured products like Rind or Reine that are more appropriate for eating on their own are less available.

In general, they are not cheese and it's not best to approach them as cheese as you would use dairy cheese.
