He sneezed a solar systen away. If that isn't casual, I don't know what is.

what guy in his right mind would give the strongest villain a senzu bean to recharge then have sin son go and fight the villain?

that solar system was decaying/dead and was about to go bye bye... so, still no. 

if you brought up superman towing a bunch of planets with a huge ass chain while effortlessly flying around in space then you'ld have a point..or even that lifting 1/3 of the universe thingy... but you didnt' so again, no :p 

now that i think about it, with all the so called heroes out there who refuse to kill and crap like that, that kind of stupidity pales in comparison to Goku's stupid line of thinking lol

one such instant

kayo sama: hey goku, once you get to planet nemic, pls, for the LOVE OF GOD! PLEASE DONT FIGHT FREEZA!!
Goku: Sure thing master

then at planet Nemik
Goku: so, where is this freeza? gonna have me a good fight... moron!

Even if it's dying, it's still a solar system. He still sneezed it into oblivion.

I think counting that sneeze as a feat is rewarding bad writing. Superman's sneeze is never consistently that powerful. If that's the case, his most powerful weapon isn't his heat vision, or his ice breath, but a sneeze -_-. It's bad writing, pure and simple. I don't understand how Superman would beat Goku, his destructive ability and techniques  are simply outclassed by Goku and Z fighters. For example, how would superman beat someone like Majin Buu or Cell. They can regenerate from anything he throws at them. People use feats for Superman but they're random and don't paint a picture of why he would win. 

Grab by neck, take into the sun at Whatever x speed of light. Enjoy the delicious smell. Problem solved. 

Bad writing or not, it's in the comics, it's there, we use it cuz it's funny. 

you have a point there. no z fighters can survive the sun.

one of superman's stupidest and most ridiculous feat is him singing and then reaching a certain note to hipnotize? shyet? dunno what really happened but i do know he sang to achieve some stupid shyet or another. 

when i saw someone post that feat as an argument, almost everyone left shaking thier heads lol

no, the planets and whatever celestial bodies were already decaying and crumbling. all the sneeze did was give it a push and it went crumbling down. just like dominos or a card tower. 

Man... Seriously. It was still a solar system. xD
