I enjoyed the last collection more; because it was a grab-bag or an anthology. I think that's a better way to read Junji Ito than to read a few hundred pages on the same concept (even tho he did vary the takes on it a lot.) The truly weird shit his brain conjures and the variety of it is way more engaging than pages of, oh she's pretty but now she has a bunch of weird heads. I think I'd have enjoyed the Tomie stories more if I'd read them sort of organically... Here and there between other Ito madness. The way I did it; (Read the entire manga in a day) felt repetitious.
But as I say that's because I bought a trade. Stories themselves are fine.
