For feel in the hand my favorite one is TÜL that I can only ever find at Office Depot. For ease of clicking the lead up and the best eraser I love the Clear Point Elite by Paper Mate. I'm a 0.7mm fan for lead, not so skinny that it breaks under my ferocious pressure but still thin enough to write pretty small notes in the margin.
I've been lost for pens for many years. I yearn to find a good one and have actually put up an ask here myself on the topic. I'll be following this thread.
For notebooks the common denominator I'll be fine with is Moleskine. Don't love it but it won't ruin my life. I sample around like crazy and 90% of what I get drives me up the wall, luckily I write every day and go through them like tissue so I'm not stuck for too long before I get to sample anew. My absolute FAVORITE notebook was from an Italian company called Impresso on Etsy -- GOD I LOVED THOSE NOTEBOOKS -- I was gifted one and bought the second. Alas they are really thick, impractical for tossing in a bag with computer, dance stuff, change of clothes, just too bulky to be a constant companion. I never even thought to check if they make slimmer notebooks until now. ON IT
