All of this is tempting me to actually start the manga....
You definitely should! It's one of the best manga/anime ever. It's actually one of my faves after Naruto.
Doesn't reading the manga kinda ruin the pleasure from watching the anime?
You can watch the anime or read the manga. It's up to you. The story is completely the same so you won't miss out anything in the manga. Just watch the anime and once you're caught up with the episodes then switch to manga 
But yeah. When you read the manga you know what's gonna happen. But still I like seeing the scenes animated
