Ah, TakaFuji and AraiKato... I can see those. Though, the fact that the natural progression of such an OTP war for you is to smush them together and get AraiFuji is a bit baffling...

See, I avoid it altogether and go for TezAto or SanaAto for my OTPs. And it's not so much a war but a peaceful coexistence as favorite pairings. :)
