I'm not a big fan of either. I've been involved in the restaurant business my entire adult life and neither one impresses me. If I had to choose, it would be the Delfield but keep in mind that their parts have to come from a Delfield supplier. Bev-Air parts are a little easier to get except for things like door hinges and door gaskets. Sorry that I can't really be much more help than this but this is my opinion based on experiences.
