I feel like, even before the transition to CG, DS9 was a little better in introducing some new designs. Even setting aside any "hero" spacecraft (DS9, runabout, Defiant), in the first five seasons, we got 3 new Bajoran ships (scout ship, impulse raider, interceptor), 2 new Cardassian ships (Hideki and Groumall), the Maquis/Federation fighter, the Miradorn ship, the Wadi ship, the Boslic freighter, the Flaxian ship, the Karemma ship, and of course the Jem'Hadar attack ship and battle cruiser.
That said, yes, "Enterprise" was able to show us a lot more new ships. Heck, they ended up giving us no less than six different Klingon ships, which is more than had been introduced in all previous shows and movies combined. Clearly, the series had the good fortune of being made in a time when buildng and filming digital models had become much cheaper than building and filming physical ones.
This also allowed them to come up with some design concepts for familiar races that hadn't really had any up to this point, like the Vulcans and the Andorians (although I think recycling a Xindi design as a Tellarite ship after only a year was a mistake).
Still a few I'm holding out for.
