Stylus note taking app?

Hi,

I am thinking about buying an active-digitizer-enabled windows tablet for my note-taking. I have not found an obvious one, so here I am, asking for help.
My only requirements:

  • pen support
  • pdf export
  • "new windows ui" preffered
I have been looking at evernote, but "new ui" version does not support pen. Another contender is onenote, but when I tried it for few hours, it kept bringing the software keyboard up a lot (I could deal from time to time, this was at least once per 2 minutes, which is a dealbreaker).
Any ideas? Thanks
