Go for what you can find the most accessories near you. I have Gladiator and slatwall. The slatwall fixtures are slim at HD and Lowes, but you can find a lot at a local fixture recycler place. I have several hooks that I use to hang sawhorses, extension cords, and other random items. The Gladiator stuff is becoming rare at certain Lowes, but can be found at all the Sears near me. They're strong and durable and look nice for a price. Looking at all of them, I think they're pretty similar except for the mounting system. I'm sure they probably hold the same amount regardless of brand. I wish the fixtures were interchangeable between the brands, or at least be able to use them with slatwall.
