Genshin has always been stronger than HSR. Your flavor texts like characters destroying galaxies or whatever means nothing when they get stopped by normal people.
Doomsday beast can destroy a planet but can't destroy a space station or humans.
Phantylia can destroy a star but not random people or the area JY and the team were on.
FF can destroy a planet but can't overpower random NPCs in Penacony.
Blade is wanted throughout the universe but YQ can stop him.
Then Phainon easily disarms the 2 people who traveled multiple planets fighting enemies that are at minimum "planet destroyers".

Which HSR character can actually beat Genshin characters? Show feats instead of flavor texts otherwise Genshin wins because Aether defeated the All-Devouring Narwhal which was said to be able to survive the planet exploding and can devour all.
