Kakashi should win via Genjutsu
Kamui or bust. Kakashi though could utilize his clone misdirectional tactics like always as long Laxus doesn't catch him off guard and pummel him.
Distance and Kakashi's reaction will be key player if he wins or not. Laxus is much more linear but physically and speedwise superior.
