"the tracks pop out for easy cleaning,"

What tracks are you referring to? What type windows, double hung, casement, slider, etc? Wrapping the exterior frame in aluminum? What glass package? What are their respective air infiltration and glass package specs? I am not familiar with either but their are a couple pros here from your area of the country who hopefully will pop in. I will say that neither brand are brands that I have ever heard any pros speak of with any regularity as being a quality window, doesn't mean they are not however. My gut says they both are a mediocre brand.

Based on price, I don't think they are mediocre. In this area, both are rated in top ten. (I don't buy windows often and so it could just be sticker shock. It does look like pricing is aligned with Anderson windows.) In Michigan, we do get some really high and real low temps so maybe we need a higher quality. I don't mind paying the money if it's for something that is needed. I just can't figure out what we really need in a window.

https://weathergard.com/ will show some of the details of the windows including their frame construction which to my limited knowledge seems to look more sturdy and makes sense. But $7000 worth of sense, I'm not sure.

Glass package is Cardinal LoE-366 https://www.cardinalcorp.com/products/coated-glass/loe-366/

Windows are mix of sliders and casement. The tracks in the sliders are removable for cleaning (which I thought was genius!)

They also offer life long warranty on the vinyl, glass seal, balancer, hardware, labor and screen repair.

I am familiar with your market and like the WeatherGard over the Wallside product If it comes down to the 2 of them. I dont particularly like the pocket sill but the Cardinal 366 glass makes up for it.

Thanks @OhioWindoze. WeatherGard quality and warranty did seem better. Being familiar with the market is there someone you would recommend we should get a quote from that might offer good qualitybut lower price than WeatherGard?
