KJay,
I haven't done a thorough search, but so far I haven't found any other relay (except the WattStopper HDR) that matches the GE in terms of load ratings, installation ease (no socket needed, just pop it into a KO), pilot-contact capability, and price.
In terms of ratings, the nice thing about the GE relay is that it is essentially the same as a toggle switch, so it can be used with pretty much any 20A load. The other relays I've looked at all fall short in one rating aspect or another, most often lacking a tungsten rating or having one that's significantly less than the full amp rating. That's important because the relay could be controlling a receptacle, which could have anything plugged into it.
