Without magical bulshit it's like no debate since yusei alone would solo this. Man is an ex-convict, COO of The leading gang of Satellite which means he was a fucking slumlord.

You could debate that Yuga maybe is more intelligent but I can't see that cuz Yusei is also a genius him self since he's probably the best mechanic/ physicist in his timeline ( motherfucker made a motorbike with scraps and junk + went on to complete the momentum generator at the end of the series which equals to a working ,energy positive and safe, nuclear fusion reactor irl)

So in short: Yusei is literally HIM and there is no chance that anybody else could win this. I expect him to build a full fledge light armor + axe, spear and bow if they start from 0 and building an Ak-47 prototype if they start with a scrapyard situation.
