Geo or DEF Post Buff Goblet?

Pretty much what the title says. I'm not a math person, so my question is, once the Hex buffs are active, is a DEF goblet better than a Geo goblet? Bc let's be honest, getting a double crit defense artifact in general is way easier than anything else. I have R1 Uraku and eventually I'll have C2 but he's currently C0(I wanted C2 from the get go but uh. It wasn't exactly worth the investment when I first pulled him in like mid 2023, I've just always loved his character). My DEF is currently sitting at around 1500 and while my artifacts aren't 100% leveled(mora 😓), the DEF sands is so I'm not optimistic about hitting 2k. Should I swap to a DEF goblet?

Thanks!
