Tough because you need to be someone who either has a 1% crit helmet 1% crit weapon 1% crit sight or 1% crit armor (Perf imperium or mod viceroy).
If not 5% crit chance is better than 4.5% crit chance with easter 21 and this ring.
With that said it really really does help out the mod viceroy with it being a pretty weak defensive armor.
Then you can run Halloween 22, Easter 23 mod viceroy netting you 14% reload 5% crit chance, probably maxed runspeed, like 10 hp and idk like uhh 8% crit dmg?
With that said I'd definitely prefer Halloween 22/easter 21 plus an ares perf/christmas 21 ring. More crit dmg with same reload and crit chance.
And dpp is king.
