GTO as someone else said.
Evangelion
Okuto No Ken (old school mad max kung fu thing, awesome)
Cobra (old school sci-fi)

My favorite are Tensei shitara slime datta ken and Overlord, I recommend both of them a lot LOL.

I heard that Konosuba is also really good, but never watch it myself.

All anime I mentioned above are isekai-type.

The more generic ones just to pass the time I would recommend danmachi, SAO as just two generic as hell but still entertaining

[Shadow870]

Hmmm. Based off the animes that you liked, I could only say Attack on Titan. If you want to explore other genres, SNAFU, and Love is War are great animes that I enjoyed. They are slice-of-life.
