Some downside for those experienced and very comfortable using a Wacom + carefully configured Photoshop brushes, same with 3D artists using zBrush.
Astropad (app) does a fairly good job letting the iPad Pro work as a tablet for OS X devices. I get a little more lag that appears on YouTube videos of it.
But, you could figure out yourself if you like it in approximately 30 seconds at an apple store; try it out in the notes app and a few other drawing apps. You'll know immediately if it's right for you.
But do you have an app that takes notes and converts your handwriting to text? I haven't found reviews of apps that seem to do that well. That's the real point of taking them digitally instead of on paper.
Onenote and Evernote are way, way worse than a paper notebook for my needs, but I can taste the chance that a working digital notebook offers. It's so close!
It has that tiny bit of latency that all ios pencil apps seem to have; only Apple Notes feels 'perfect' to me right now. And, the paper texture / materials in Notes are better; the Notes pencil tool is just about perfect in my opinion.
On the plus side, I liked having all the different graph papers, the notebook features seem to work well, and marking up a pdf was fine.
I'll see if I reach for it next time I'm taking notes, but right now it's neck and neck with Apple Notes for me.
