I'll pile on here, Okna 600 is the choice, I'd go triple pane.
With or without the tax credit, Energy Star in colder regions starts and ends with triple pane these days(with rare exception). Its on the verge of becoming standard issue IMO, I would not want spend $20k on high performance windows with a 30+ year service life that have dated glass performance within the first few years.
Window (in)decision: Harvey Classics vs. Okna 600s vs. Marvin Essentials
