i can see that there are a feew rooting tools here.
soo what is the difference between them?

They are all similar except for Method G (the one that says 'Try This One First'), which is installed via APK on the phone.

The others are run on the PC while your phone is connected via USB.

Some of them work with some phones and won't work with others. That's why there's different tools posted.
