Should I use my thumb for this...?

It's amazing that you achieved ALL PERFECT with your thumb! It's really impressive to see you find and prove your own efficient method. Can we expect your perfect skills again next time, Jangine13?

It seems like it keeps getting skipped when I use my index finger ㅠㅠㅠ

When I used to play the rhythm game Love Live!, my thumbs would often miss notes, so I switched to my index finger, and it worked much better. I guess note recognition varies from person to person.

I played both, but All-Stars had aggressive monetization, so I just played it on and off. For School Idol, I played completely free-to-play and completed every event. My rank was probably around 300 back then, but ultimately, both games were removed because of All-Stars.

Yes.
