The only one I really got into and read extensively was a really shitty one about neopagan bullshit called Oh My Gods.
I found it around the same time I was informally studying various religious beliefs around the world so it kind of caught my interest as a lighthearted take from someone in one of the communities I was studying rather then some dry history and text books written by academics.
Sort of was the right comic for my headspace at the time, but now that I am not in that headspace I can't really see how I got enjoyment from it as it just seems so shit now.
