I don't get that at all. I used to work in MI sales. We carried all kinds of basses. I have owned and liked all kinds of basses.
My customers would play a Smith bass and say "It looks and sounds amazing! But it feels weird". I agree. Pretty much the only guys who drooled over every aspect of a Smith were gospel players. In the late 90s and early 2000s gospel guys thought the Smith was the end all be all of basses.
But it has nothing to do with not being a Fender (or feeling/looking/sounding like a Fender).
The feel of a Smith is "extreme". It's not extremely "wrong". But it's VERY different from most basses. So, even if you're coming from an Ibanez, Sadowsky, F bass, etc. it's going to feel odd.
I think everyone agrees that fit, finish, and construction of Smith basses are superb.
