What is the best school romance anime you have seen?

Recently I have been watching a lot of romance anime and was wondering what are the best ones to watch. Thanks to all those that respond.

Edit: Due to all the responses I saw that I should probably state the ones I have already seen.

Here is a list: Kimi no Na wa, Fuuka, Kokoro Connect: Michi Random, Masamune-kun no Revenge, Nisekoi, Shomin Sample, Mayo Chiki, Toradora, and Oregairu (Season 1).

I am currently watching: Gamers, Tsurezure Children, Oregairu Zoku, and Youkoso Jitsuryoku Shijou Shugi no Kyoushitsu (Don't know abbreviation)

Thanks.
