As I look at it, I think the MicroRocket will sit a little lower, but I'm not sure. The perspective makes it hard to tell in the second photo on my blog.
Folded, the MicroRocket will clearly be more compact -- take a look at the third photo.
I'm disappointed that they didn't do more with the pot supports, like making the tops level so that there's more contact with your pot, but strengthening them is a step in the right direction.
