kilt, I haven't seen both to compare, but sometimes the "findings" at Walmart are crap from China. Grommets are not all the same, you want to try comparing the quality of the metal, see if it has been well formed or has rough edges, see how well the parts and die will fit. And whether it will seat nicely on your fabric, or need an extra layer to reinforce it, etc.
Working with some large plastic ones this afternoon actually, and while the supplier says "one layer of fabric" I've used three, and they seat very nicely and firmly without cutting anything. I figure, reinforcing can't hurt, grommets never need any excuse to tear out.
