I'd put W2 in the "Extremely Close... but no cigar" category. One of the things I really love about Indy guitars is that the W2 feels very close to being a Jem neck. It's thicker, obviously, than W1 so you can really dig your fingers into those notes!
As far as being the "same"; no, not exactly. The different radius makes W2 feel more boxy. I think the prevalence of neck binding on W2 makes it worse. I have a maple fretboard W2 that feels much better than its rosewood counterparts with binding.
And, yes, it goes without saying that you'll see better craftsmanship on a Jem.
