I find that they’re great for headings, titles, dates, etc - a little emphasis in my notes. With that said, my pilot metropolitan’s stub nib has also always been really scratchy too, and hard starts a lot. It’s always been one of my most disappointing pens.
One of my favorite stub nibs is a Jinhao 80 (Lamy 2000 clone, usually sub-$10). I swapped out the Jinhao nib for a Lamy 1.1 stub, and it writes like a dream!
