I'm a really big fan of National brand engineer's pads.
I write with a Lamy Safari Fine nib or a Pilot Metropolitan fine nib, both loaded up with Noodler's 54th Massachusetts. No issues with feathering, and no bleed though with the Pilot. There's on occasion a little bleed through with the Lamy, but it's not that you're using the back of engineering paper anyway. As long as you're not just resting your pen on the paper, it's fine.
The National paper is good with pencils and erasing too. . .if that's at all important.
If you use a fountain pen, get this one: https://www.amazon.com/NATIONAL-Brand-Computation-Sheets-42389/dp/B0017TMB64 All the other papers tend to be fuzzy / will gum up your nib.
I expect I am in the minority though.

For notes I buy a ream of copy/printer paper from the office supply store, they sell reams that are already 3-hole punched, it's not very much. I like having no lines interfering with anything I draw. Everything I lay down on the page really stands out against a pure white background. I suppose I take my time and write clearly, what simple sketches I do make, I take a second and do it clearly as well. The result is clean notes that are easy for me to review later.
I also write with .7mm pencil and use Staedtler pens in one or two colors to add emphasis.
All my homework gets done on National Brand engineering paper. ...Found a brand I liked and I stick to it I guess...
Each class has its own 3-ring binder and I load each one with a bit of this plain white paper, and a bit of my engineering paper.
