Main difference is the SLX line is a stripped down version. They have gas only water heaters, no thermostat on ac, plain finish, etc. we just traded our 287 SLX for a Jayflight 29 bhds and don't regret it. Look close at "standard" features on both before deciding. Not that one is better than the other. It's strictly based on YOUR needs. Build quality is equal imo.
