Hi coolny29 and mim,
I cannot give you a direct comparison as I've never personally sailed an Element, but I know that the NCX is a really sweet sail.
I would have said the NCX has a softer feel and could be more forgivig, but I can't make that comparison.
Mim likes the Element for about the same reasons it seems.
The cambers may or may not make the Element more difficult to waterstart or uphaul.
There are +'s and -'s on either side of these issues in the camber vs no-cam debate.
I like no cams for entry level sailors because the normally are simpler, and a little easier to rig correctly, and there are no cambers to break or malfunction.
Hope this helps,
