Been so long since I've seen TAS, I'm not sure, LOL. I do like that Enterprise
explored some races from TOS that the other shows didn't, like the Andorians and Tellarites. And some people take exception to Ferengi and Borg and the Observers showing up, but they all worked fine for me within the overall Trek framework.
Plus, y'know, Jeff Combs. Always a win.
