I have to say that I had not looked at the triple R product before, the fit and finish looks exceptional. Where I live, near the coast, no question of what I would have to pick.
On the powdercoating, you did ask if chips would be easy to touch up. My answer is yes and no.
If there is a chip because of mechanical damage, yes. But if the chip is because moisture has gotten under the coating, and created a "blister" and that has "burst", then repairs, in my experience, require removal of the coating in the area and around it to be sure you have gotten all the moisture and/or rust.
Again, all back to humidity in my opinion.
