I just have an I, but like others here it's the only one I've tried. I love it. I use blue box 3.5s and they work beautifully. After all the rave reviews I'm really interested in trying a J now, but they're pretty hard to come by these days, everyone seems to be sold out and proud owners aren't parting with them. Really good mouthpieces.
