keyword tool advice

Hey everyone i have just purchased a couple domains that i really like but have been only using Google's keyword tool, but i was wondering if anyone has any advice on some other keyword tools that could give me better stats before i finally start my campaigns. I've done some research and found a couple other tools that i like keywordeye, keyword snatcher and seocockpit. has anyone else tried these and if so which ones have brought the best results?

I'm using Longtail pro and Market samurai.. both tools have the free trail, Just try with these tools.
