The most energy efficient, air tight, and maintenance free will be high end vinyl.

unlike the cheap looking vinyl windows most are accostomed to seeing in home improvement stores, building supply stores, the windows used by the jack of all trades contractors as well as the “family friend”, there are a few brands that many window pro’s seem to always recommend and install themselves.

a few of those high end brands would be Sunrise, Okna, Soft Lite, and Kensington. Unlike cheap vinyl, these brands won’t warp and actually have higher structural ratings than wood windows.

in fiberglass, Marvin Infinity is well regarded although the performance numbers wont be as good as high end vinyl, particularly air infiltration ratings. the pella impervia ( fiberglass) is flimsy, cheap looking, and garbage in my opinion and not many pro’s take the impervia seriously.

You also have composite windows. Starmark windows are beautiful and very highly regarded although more expensive than high end vinyl.

No website really exists like that. You are probably on one of the best ones right now for comparative analysis, but you have to read it in text vs. see it on a chart.
