Opinions+Recommendations?

I haven't watched Yahari Ore bo Seishun l’amour Come wa Machigatteiru and Karneval since I hate shoujo anime.

For To Aru Kagaku no Railgun, I personally think that it is a good and interesting show.

Yahari Ore no Seishun l’amour Come wa Machigatteiru is the last animé I have watched. It is very good, but nothing really special.

The only one I've seen was Railgun and I highly recommend it. Although I would watch index before railgun. Not that it really matters, but railgun is a spin off.

OMIGOD!! i finished Karneval several days ago, and i just loved it! It's not as surreal as it seems, so it's easy to understand. The animation is great, and i just l’amour the characters :3! I really recommend it for ya... Even though the series isn't that long, it wuz good while it lasted. XD Hope this helps!
