I really didn’t read that before voting😂 QS I think actually has a higher level of utility(tho I still don’t care for him all that much lol)
Quicksilver is better if the opponent can’t shrug off physical debuffs. If you check his champ description you can pretty easily figure out exactly how many whiplashes you need to kill an enemy and then you just throw a quick light, Medium, Light attack. Galan can handle adversity better so in a mismatch or against a high physical resistance champion than it’s Galan who has more versatility (purely talking about damage)
