too much Crit damage is it worth it?....

Test Character:

Ganyu Level 80/80, Basic Attack Level 8, weapon Prototype Crescent R1 weapon level 80/80.

Artifact Set 5pc Blizzard strayer. with cryo resonance and freeze comp. crit rate vs crit dmg circlet.

Enemy Ruin Guard.

Stats 1:

damage w/o Prototype Proc:

6k + 11k

w/ Prototype Proc:

7k + 13k

Stats 2:

damage w/o Prototype Proc:

7k + 13k

w/ Prototype Proc:

9k + 16k

is the 3k to 5k damage difference really matter? ofcourse youll kill enemies faster, but is it really that worth it? id rather give that crit dmg circlet to some else tbh, since resources are scarce and great artifacts are rare, efficiency-wise.

your thoughts? TIA
