if by durable you mean, who would blow up first under ki blasts then Goku. But Frieza would survive longer than Goku would cut in half I'm willing to wager.
Being cut in half isn't a durability ft and Goku has had holes blown through his chest and he was still fighting. Trunks had a hole blown completely through his chest and was still living as well. Who can withstand more between Goku and Frieza?
When did Goku fight with a hole in his chest? He was killed when Piccolo blasted him and Raditz thru the chest. Trunks died pretty quickly after getting a hole blown thru him by Cell. Vegeta dies when Frieza lasered thru his chest too.
Frieza can survive injuries that would put Goku in Otherworld so if that's what you mean by "who's more durable" then Frieza takes it.
Not only did Frieza survive being cut in half, but also Namek's explosion, while in a dying state before his father picked him up. Plus unlike Goku he can breathe anywhere in space. This shouldn't even be a debate.
Frieza's physiology is different from Goku's, hence why he was able to survive with his wounds in space. However that would fall under constitution, and not durability which carver9 is interested in.
Well super Saiyan Goku was able to block a sword with his index finger...
The same sword btw that hacked Frieza into pieces so i guess it really just depends on what Carver is looking for exactly. Surviving being cut in half is pretty durable too
Surviving the wound is though. Goku wouldn't have. Back in Dragon ball yes. That doesn't compare to getting sliced in half. Umm he lived for a little bit I guess. He was on the ground hacking blood and then died though lol.
Frieza and Goku fight proved who was more durable. Goku withstood more and lasted longer in that fight. Whatever Frieza can withstand, Goku can withstand as well. If first form Cell was to hit Frieza and Super Saiyan Goku with the same attack, Goku would handle it better.
During their fight on Namek it's possible Goku was doing more damage to Frieza than Frieza was returning. So technically Goku wouldn't have to be more durable. After that tho Goku's durability in SSJ1 sky rockets.
Are we talking Goku on Namek or Goku at some later stronger point in SSJ1? Cuz i'm pretty sure now his SSJ1 is more powerful than Perfect Cell but it's still just SSJ1
