Keep the pin coated to prevent rust.
A can of WD-40 is your friend for exposed locks. Give them a periodic "hosing out" with the spray tube which will flush dust and moisture out.
I'm still using a locking pin that was sold under the name "Valley" that I bought about 20 years ago. Still works flawlessly and it's never had a cap on it. Have had the key on my key ring so long the raised "Valley" lettering is 90% worn off.
As for different brands offering something better, they all are a variation of the same thing. Essentially a spin-off of a basic padlock with the pin being half of the shackle and the lock being a padlock body with only one hole.
