@StargunZX: I'm very well aware of what they did. However, power scaling doesn't work against comics. Whom debates using feats, not assumptions nor speculations. Also, Goku can't survive in a vacuum, Wonder Woman can. If he does decide to destroy Namek (Which goes against his character), then he's suiciding himself. Using the power scaling logic, Goku in SS3 might be able to bust multiple solar systems actually. However, this is again, based on speculation and assumptions. Why is it multiplication? Can it simply just be addition? Can other factors like Vacuum take place? Can mass and density have a say? What about Gravity and Electromagnetism? Time and space? Kid Buu destroyed an entire galaxy by destroying worlds and using his IT to teleport world to world, it's not like the entire galaxy disappeared from existence. If this were the case, his fight with SS3 Goku would've been entirely different.Going by that logic Freeza and Kid Buu would be the two strongest canon DBZ characters in cross fictional debates since they're the only ones with planetbusting feats to their names, and by the same token Goku who has never done anything close to destroy a moon would be bellow Muten Roshi and Saiyan Saga Piccolo in destructive power.
This is of course a wrong way to go when debating DB since most of the characters there share pretty much the same power set. Sure there are some particularities like regen for Cell and Buu but in general their abilities are the same, specially when it comes to strenght, speed, durability and blasting power. So given that Freeza is able to nuke planets logically characters who are confirmed to be stronger than him should all be able to acomplish (at least) the same feat.
