Gas vs. Electric Ovens

We have always used electric ovens, but recently we made pizza in a friend's gas oven and were puzzled when it wouldn't heat as hot as we wanted it to. Then we broiled a dish in another friend's gas oven and there too we found that the oven didn't get as hot as our electric model. Now we're curious - are temperature instability and draftiness common in gas ovens? Our next place will have a gas range but we're feeling hesitant about the oven.

What sort of oven do you bake in, and how do you think it compares to the other sort?
