You are comparing apples and oranges. Milgard is a vinyl window (medium quality) and Andersen 400 is a vinyl clad wood window (again, medium quality). If the Integrity is competitive, it is better than both.

Yes, agreed on all points. Was more interested in performance and durability differences because aesthetically we would be happy with either. But it turns out the Marvins are EXTREMELY competitive so it's a no-brainer, we are going with Marvin. Both the wood Ultrex and all ultrex are in line with the Milgard Tuscany quote, and that is with Milgard being mostly single hung and a few picture but Marvin being a mix of double hung and casement. For those who may read this in the future, we are in TX.
