Try something new. There are a lot of shows out there, and if you never seek change neither will you ever be satisfied. Everything else will be inferior to the original.
on another note i'm pretty sure you'd like komi can't communite.
There isn't any other anime that is like Nichijou. I have not seen Yuru Yuri but I'd figure it maybe a bit similar, Azumanga Daioh is also a little similar
