Hmm, there are actually more differences than just the nozzle. The trigger/air valve is different between these two models. I personally feel the HP+ trigger is much nicer than the Eclipse
. For me, the choice would come down to what I mostly wanted to use the brush for. The Eclipse is a very good general purpose brush. It will throw a bunch of paint, and is also reasonably good for detail, once you get a good feel for it.

The Eclipse will be more forgiving in regards to what paint you use, and reduction, the HP-C a bit more finicky... Not much, but some. Really, you can't go wrong with either one - The Eclipse is built like a tank. The HP-C a little more refined, and delicate
