Oven vs. Mircowave

Why when you cook stuff in the oven, It taste better than when you cook it in the mircowave?
Like when i cook pizza in the Oven in come out all crispy but when i cook it in the mircowave it come out all soggy nd mushy..... Just nasty but like i dont feel like waitin 30minutes when i can cook it for 5minutes  YA FEEL ME!!!
Like now you can steam Vegtables in the mircowave?
