Do you have a specific question about the Web's ones? I live by their store, and go there all the time. I've never used those needles, but I've seen them, and can inspect them more closely the next time I'm there.
It looks like they only have 7 needle sizes in that Webs set. Does the other set have more sizes? If so, I would go with total-number-of-needle-sizes, over range-of-needle-sizes.
I just bought a new set of Boye Interchangeables. I had an old set from the 60's that had 9 sizes. The new set has 13 sizes! Going all the way down to size 2 needles! It also has thinner cables, which looked good for magic loop knitting. The cables are a bit stiff for ML knitting, though, rather to my disappointment. Not that I really do much ML, I prefer my DPN's, but I thought it would be cool to have a set that worked for it. No biggie. I LOVE the compact carrying case, and having so many needle sizes!
