Obviously not always an option to use an oven/stove if you are e.g. bringing a packed lunch into a typical office. It’s certainly a better option for some things (you will never get “crispy” from a microwave, period) but microwave still produces acceptable results for many things, particularly if you are willing to put some thought and care into how you use it.
That is why I do most reheating on the stove, in the oven or on the contact grill (depends on what it is).
