Seamless is definitely better.

I bought mine from years ago and haven't looked back.

I use this one:

I have another one that's supposed to be used for wet combing, but I guess they don't carry it anymore. Darn shame, because it's an excellent comb.

The euro-stil Rake jumbo comb looks a little like it. It's supposed to be good for use on long thick hair either wet or dry. Hmmm, maybe I'll purchase it.
