I'd say it's about the same difficulty, just make sure you have teams you can swap between with members.
Dodging, doing ults, using EX specials into swapping to different characters.

I think the major factor is not getting hit, it resets your combo meter by a bit.

I got to Floor 70 and all the badges/rewards with M2 Miyabi/Trigger/Astra, Yixuan/Pan/Ju Fufu(who doesn't even have 3400 ATK sadly).
Used SS Anby/Trigger/Astra a couple times but it's just really difficult at higher levels to know when exactly to dodge because the Yellow/Red prompts disappear and enemies can go from swinging to hitting in milliseconds.
