Fran,
Of course if you compare drum kits having the same name in both keyboards there's no big difference, but did you check the "New Pop", "New Rock" and other "New Xxx" drum kits of E-60 and compare them to the corresponding Pop, Rock, etc. drum kits of G-70?
As you say, it's always a matter of taste, but to me the "New Xxx" drum kits sound more natural and expressive.
