I own several Lamy, Pilot, and Platinum.
If you ever write with a Pilot Custom 823 on decent paper, you will never be able to go back.
(If you enjoy the friction in writing, you need to try Lamy Al-Star/Safari fine nib, or Pilot Metropolitan fine nib. Medium nibs are smooth and some people don't like that.)
And even as the prices are high, they do last literal lifetimes.
