I've never had an over the stove type so I can't comment. I will say I bought an inexpensive Hamilton Beach at Walmart about a month ago because ours died. This thing is the LOUDEST microwave in the history of the world. It seriously screams at times when you are using it.
Just a heads up if you go with the counter top model. You might want to read some reviews or something so you don't get stuck with this haunted thing I have.
