Which is a better replacement window?

Simonton 9800

Pella Fiberglass

Marvin Fiberglass

I know two of these are fiberglass but I have a customer who is shopping the three of these windows. Wanting to replace 20 old Anderson's.

Thank you.

How about for replacement windows?

I am a builder in Western Virginia and we are looking at using different windows in our next 5 houses.
Who makes the best fiberglass windows in double hung?
Who makes the best vinyl window in double hung.

I am not concerned about price. Just superior quality and thermal performance.

Thank you.
