He can only seal one type of energy though....Like he was only able to seal Naruto's kyuubi chakra, and not Naruto's chakra, to delve into it deeper, I believe it was also stated he was only able to seal the Yin(might be yang I don't remember) chakra of the Kyuubi.
Yusuke is much like Naruto, he has two energy sources; demon, and spirit.
Nothing that Minato has shown makes him faster than Yusuke, other than his Flying Thunder God technique(the teleportation one).
Strength, speed, durability, stamina everything goes to Yusuke, outside of maybe smarts, but Yusukes intellect goes up quite a bit on the battle field.
It's not just that, but his strength, and destructive ability, along with stamina and ability far exceeds anything Minato can do, even with the power of his Summons. The only thing that can be debatable is speed, but like I've said, nothing of Minato's base speed is even close to Yusuke(he travels several thousands KM's in the battle with Sensui in seconds, and this is what 3 years before the end series?), and it's just his Flying Thunder God technique along with his space time warp ability that gives the illusion of a fake speed.
So Minato's only real advantage is smarts, but even Yusuke isn't that stupid in the battle.
Urameshi wins in seconds.
