I've been reluctant to dive deeply into digital until I feel confident with traditional tools.
Here's my list of favorites:
Pencils: Palomino Blackwing 602
Mechanical Pencils: Uni Kuru Toga
Fountain Pens: Lamy /w EF Nibs (I've tried a lot of fountain pens over the years and always end up going back to Lamy. A $20 Lamy beats a $100+ Waterman)
Hunt Quills for fine details
and a variety of sizes of Winsor & Newton Series 7 brushes.
