I liked Suplexmentary the best. On the pages you tested white looks better than black (but obviously black will be better on lighter pages). I think stylistically it's best font it's also the easiest on the eyes.

If you decide to go ComicNote, watch out for the lower case "i". If you could make the "i" look like "I" instead it would look really good (some software lets you mix fonts). That's the only thing that really bugs me about it from a style standpoint, otherwise its a good looking font. It will prob be a little tougher to read on the phone compared Suplexmentary. I'm looking at it on a PC right now though so I can't tell for sure.
