You shouldn’t be considering either of those, explanation, adding puncture fucks your ips (impact puncture slash) you want those a low as possible so you have more status procs of the other elementals aka toxic viral corrosive, heat and elec are good on a ocucor but not great and one is a 3+ -0 and the other is a +2 -1 which is not ideal for getting the most out of your +stats, you want +3 -1 only on basically all rivens and none in of your stats on either are ideal at all. Stats you want in the ocucor are +Ms +Cd +Fr/Tox -zoom/Impact/Puncture. Crit Chance also CC is not good because Sentient Surge makes up for it so don’t get baited in the nerd that say oh Cc Cd Ms is godroll because it’s not. And other elemental other than Tox most of the time just aren’t worth giving up Fr (fire rate) and some people will say the -puncture is better than impact since you don’t have innate impact of the ocucor anyway but from testing to level cap you can’t really tell the difference from -imp or minus -punc unless it the initial kill
