Opinions on Rochester Colonial vs Wonder Window (details inside)

We have narrowed our replacement window choices to Rochester Colonial installing Marvin Infinity (fiberglass) or Wonder Windows installing Okna Starmark Evo. A total of 10 windows. Rochester Colonial’s quote is 4k more. Anyone have opinions on these choices? I liked both of the a lot but I am not an expert! Would the Marvins be worth about $400 more a window? Thanks for your thoughts.
