Calphalon vs. Circulon

So my mother got me to register for Circulon cookware which she swears by. As I was reading more and more about it, should I go with a stainless steel calphalon set instread? Is that better than circulon?

Any input would be great.

Thanks!

My mom had circulon for years. FH was in charge of choosing cookware, since he's the one that uses it more, and he researched and found infinite circulon was better for non stick. I always thought calphalon would be better, but he said the circulon was.
Don't know about stainless though! We have a set of stainless emerilware and I've had no problems. It's made by all clad, but their regular stuff is very $$$$$.
