The specs seem very similar, and not having played a
Warmoth neck I cannot be confidednt in my answer.
But I think things will feel quite the same, your thumb and the gap between your thumb and first finger are what really make contact and matter with necks.
Anything after that is down to the
fretboard radius.
The Warmoth neck is probably not multi radiused like the JS neck (although atually I know they do them), but to be truthfull I don't really think the mutli radius makes much difference if you're a confident player.
What you can be assured of is that Warmoth do make very high quality necks and even if it takes a little extra practice to play what you want to you will be a better player for experiencing it on more than one neck profile.
