Nylon vs Plastic Spacers

What are the benefits, differences, and downsides between using nylon vs plastic spacers?

Plastic spacers compress over time, if you can fit nylon spacers, they’re better in that situation. They also have a bunch of other convenient uses (chain rollers, C-Channel Structure, etc.) I bought a 200 pack from RoboSource at the beginning of the season, haven’t looked back.
