Shanks reigns supreme. Luffy haki is getting stronger and stronger but still not as Shanks, but lets ignore that considering Kaidou said the haki conquers all and we know how that fight went... Anyway, even with gear 5 for the point of plot Luffy can't beat Shanks. We know the fight will come sometime (Luffy's haki gets stronger by the arc so he will be as strong as Shanks by that point because he will be better at haki and gear 5) so when the fight comes I think Luffy will win. But currently I love D. Meat will lose against I need D. Screentime.
