which season is best of sao season 1 or 2?

I haven't watched the second season but I did like the first one.

I loved the 1st season but I didn't really like the 2nd season. The 2nd season just got...strange, and it wasn't that exciting to me. But overall I still think SAO was a good anime put together.

But 1st season is the best to me!! It had better plot, more exciting fights, I liked all the characters, and it had such a cool concept.
