I'm partial to the Agency Publishing titles. Especially The Agencies: Frontiers. Issues 6, 9, and 10 featured a wonderful tickling machine called The Carousel.
All the rest is up to personal preference, but these are truly the best, IMO. I used to love MTJ but it has been a while since I bought and truly enjoyed one of their comics. They still have terrific story authors like Kunzite, but comics-wise, each release is no longer the amazing "auto-buy" they used to be. The problem I have with them is that they have become a bit formulaic and stopped featuring edgy sadistic tickling. Everything is done is a playful kind of way which does not appeal to me as much. It is somewhat mitigated by Bandito's talent at crafting funny, somewhat parodic stories, but it does not quite scratch that itch like it used to. I miss Bohemianne, FTKL, Mandell, etc...
