Roshi vs Genkai

Master Roshi vs Master Genkai. I've been rewatching Yu yu hakusho and it got me thinking, which one of these combatants would win in your standard tournament setting. Roshi probably has more raw power, but genkai has the advantage of being hot. Who wins?

Roshi is arguably more powerful than Demon Yusuke.

Genkai gets flattened by Roshi without breaking from Jackie Chun.
