I can't compare all those balls and only own the RG Grenade and a Storm Super Natural. The Grenade is drilled Rico, and is very smooth, rolls a long, slow arc. The SN is drilled pin over and although it goes long, the backend is pretty strong. I do use the SN as my dry lane/spare ball, but because of the backend, I sometimes whiff the ten pin to the left, LOL. But that's just me. I gave the Grenade to my son.
