>>1131637I disagree that 1827 has the best artists despite being the most popular pairing, that title is for D18, seriously. I would love to draw D18 myself but I'm so intimidated with the tons of great art it has. I mean if a pairing gets people gets lamenting that they have such gorgeous art and they don't ship it constantly is pretty funny.
However, I find that the better written doujinshi are usually 5927 surprisingly.
Oh, my current OTP is 6927 although it switches with 5927/2759 depending on my mood, with 8018/1880, D18, 10051 trailing. Although I'm pretty much a Tsuna-bicycle fan who love almost all Tsuna pairings except the one that would be canon, 27K.
