i'm sceptical.
FL comes with what you could call a starter pack, right? well, guess what defines the 'FL noobsound'.
you can make unique sounding music with it no problem, but it's a rare thing to happen, esp. when made by newbies.
with people putting in that bit of extra effort to collect their own set of samples, synths and presets, there's simply a higher chance for more sonic variety.
that said, i'm sure i would've enjoyed some kind of 'essential pack' as a newb. i think what i'm having trouble with is making it an official oc remix thing, implicitly suggesting 'download and you're good to go'.
something like a collective sound library would be a nice project tho.
