For note takers, I highly recommend Goodnotes 4, for the following reasons:
- it completely disables touch and only accepts pen as writing input, you use touch for zooming and erasing;
- it allows you to pick "ball pen" which ignore the pressure variation. This make writing looks a lot better;
- it has a Mac desktop version, which allows you to drop files (to sen to iPad) and pull files (to archive files on Mac).
There are two disadvantages, 1. the apps are not free and 2. it changes the file format to .gootnote. When you export the file to PDF. All annotations become permanently etched onto the documents and you lost the ability to ever modify them.
Exact reason why I use Microsoft onenote instead..........
