What is Reddit's opinion of Guns GirlZ - Mirage Cabin?

From 3.5 billion Reddit comments

That wasn't their first game either (there's a reason it's called "Honkai Impact 3rd"). Guns GirlZ / Honkai 2 from 2012 is their earliest title that's still playable in English I think.

not sure if you've tried both, but what's the difference in these (ref - Gun Girl)
