For simple note taking, Notability is probably better. I mostly use ZoomNotes for notes (obviously) on a Cornell Notes template and for quick mind maps or when I don’t want to use iThoughts. I love using the Whiteboard and subdocuments, links to Agenda and/or DevonThink and there is so much more I haven’t even tried 
The UI is a bit of a mess and there is a learning curve. But whenever I wanted to try something, ZoomNotes could do it.
