Hmm Toradora, Oregairu (My Teen Romantic Comedy SNAFU), and Golden Time are all fantastic if you like intelligent romance comedy with drama thrown in.
Some less popular ones I would suggest are Mysterious Girlfriend X (little niche, but I liked it), and Saenai Heroine no Sodatekata (How to Raise a Boring Girlfriend).
