Sounds like you moved from one nice system to another!
I pretty much moved over to a 12.9" iPad Pro + Pencil when they first came out. It replaced my "system" of doing derivations on the blank side of the leftover cover pages from the department printer. They were then "filed" into a giant pile in the corner of my desk.
Some part of the chaos of this system was deliberate - unbound sheets that you only write on one side of are great for derivations as you can lay out many of them on a desk to see what you wrote a few pages ago. Still the iPad is a vast improvement for me, even if you can't see everything at once.
Also I don't think the iPad Pro would improve things for you, it's great if you're used to the wonderful Bic Cristal, but you definitely won't get the precision of a super fine pen, though maybe the newer generation is better on that front.
