Walrus Eras vs Boss JB-2 (Angry Charlie)

I'm having a hard time understanding both pedals and I don't know which circuit Eras take inspiration from, while it's obvious the Angry Charlie is a JCM800. I also can't find a comparison to both. I know people usually recommend rat distortions but I personally don't like the sound of the rat that much, It's good, just not my thing.

Which one of these two do you think is better for a high gain distortion?
