Stovetop Cookware - Pyroceram or Visions

Hi,

I'm interested in purchasing a stovetop cookware and I'm little confused between Pyroceram and Visions. Both seem to be old brands which was reintroduced recently.
They both seem to have the same functions. So except for the looks does anyone know other than the looks; which is better in terms of quality? I dont mind any look both white and transperent is okay; but I'm looking more for quality and ability to absorb thermal shock.

Thanks.
