YMMV, but we got
this one to replace our ancient one. It has a sealed surface around the burners, so stuff won't go under. (There was about 1/2" clearance all around the burners on our old one, and all manner of junk just slipped through and lay under the top.) The big thing that sold this was the middle burner griddle thingy. We really like(d) that.
Having said that, it was on sale when we got it before Christmas. Its current price would probably have knocked it off our list.
