Upload continues to matter more. Take Windows 11 and its fetish for syncing everything up to OneDrive by default. Offload 50 GB of photos from your phone to PC, and automatically the PC sends a full copy to OneDrive. About 6 hours on 500/20 cable, but under 10 minutes on gigabit fiber.
Backup a TB of misc stuff to Backblaze and it’s 2 hours on fiber, versus 4 days on cable. I don’t do big uploads very often, but when I do I’m thankful for the speed.
