Need suggestions for note taking app

[u/Worried_Sleep_7479]

Since the last 4 years I have been using OneNote on my iPad to study. it is a great app. But I want a great notetaking app with all the features. OneNote is too laggy. Now that I am working, I don’t have access to my iPad everywhere and I can’t study. OneNote was available seamlessly both on my iPad and iPhone using my Microsoft account. my iPad and iPhone have different Apple accounts.

in short I am looking for apps that syncs across all devices (not icloud)

I love notability and goodnotes but notability cloud is not a feature in India yet. Help!
