I think, accounting for the Single IP Themed Lands I've visited (Pandora, Cars Land, Galaxy's Edge East and West, Toy Story Land, Hogsmeade, and Diagon Alley . . . even Toy Story Playland at DSP, if you'd count it), the one that comes closest to Harry Potter in Disney's collection is Cars Land. It's the one that most literally, completely, and satisfyingly transports you to a specific place and time that is exciting, engaging, and makes you want to come back. Which is very impressive given that Cars is the franchise on that list with the least love in the public imagination. They stepped up and did it right in almost every regard - though I do wish that outside of RSR there were attractions that were more involved than the "flat rides" that flank it. And I'm still waiting for the planned Sci-Fi-style Drive-In Restaurant that would just be perfect for that land. Still, I think that's the land where Disney came closest to clearing the bar Harry Potter set.
Though I will say that I think as a land Hogsmeade PALES in comparison to Diagon Alley - Forbidden Journey is the best attraction in the Harry Potter suite, but Diagon blows Hogsmeade away as a themed environment. It's a little annoying that Diagon is such a rich and fully realized land while the area with Hogwarts Castle feels like it got the short end of the stick in comparison. The land feels like Cliff Notes compared to Diagon Alley. I understand why, but it makes it feel like the priorities are out of balance. And I think the world has made WAY too big a deal out of Hagrids. But I think I've drifted off topic!
