Ishiki no doubt, that jutsu is built specifically for disadvantages although I like rinnegan abilities I would love to shrink myself and the rinnegan couldn’t beat kurama since ishikki dojutsu can shrink non living thing and kurama is just chakra he’s dead instantly

I feel like Rinnegan has a more fun moveset. You could have parts of your body turn into a robot. Summon animals, bring back the dead, pull or push things to/away, create moons, take souls, absorb chakra, repair damage and a whole lot more.

Both

Isshiki’s dojutsu is like Brainiacs machine from dc comics…I’d prefer the rinnegan tbh whether it’s basic or like Momoshiki’s, Urashiki’s, and Sasuke’s rinnegan 😅
