All the windows in our house have been replaced by either Anderson Renewals or Sunrise.
I greatly, greatly, greatly prefer the Sunrise windows in all aspect. They are more attractive (I find the Renewals to look very clunky and bulky), the Sunrise windows are easier to operate, they are better at insulating (based on just feeling the windows and area around them), and they were slightly cheaper.
My house is 100 years old and has over 30 windows in it. We are contemplating replacing one of the Anderson Renewals in our bathroom with a Sunrise window just because I can't stand how shoddy the Anderson window looks in there... something about this one seems to have held up much worse than the others.
We also had two windows that were so big that neither Anderson nor Pella made a replacement double-hung large enough (this was 2005). Sunrise did and they are my favorite windows in the house. Gorgeous. Sunrise also measures and manufacturers to the 1/8", both Anderson and Pella were to the 1/4". I think that is part of the reason their windows operate so much better.www.sunrisewindows.com/
