Anyone have experience with the Kolbe Resolution window?

I have decided between the Simonton 5500 and the Kolbe Resolution series. Just by specs and seeing the units. And its what our local lumber companies and carpenters install most in the area. I read all about the Simonton but have never heard anybody comment on the Kolbe products. I have dealt with the Kolbe wood sash replacements. But I think I will be going vinyl this time around. Thanks for any input.
