Okna vs Wincore vs Provia for small rental

[mvrbvr]

Looking for Opinions on Okna(600 series) vs Wincore(5400 & 7700) vs Provia (endure).
We own a 4plex in South Jersey and do not live there (all on 1st floor). The windows are probably about 30 + years old and time to replace.
Not sure which would be the best bang for your buck and not sacrificing quality.
There are 7 windows approximately 44x77. All white no grids
Wincore-5400-$5991 and 7700-$6583 no capping involved but capping would be an additional $1346
OKNA 600 Series-$6965-no capping involved and installed from inside. Another quote-$7070 but all capping included-installed from outside
Provia-Endure-$6370-installed from inside-capping of window sills only

It appears that all warranties for rentals, cap it at a 10 year warranty. This is an older home with very high ceilings, new heaters were installed but wanting a good quality window to maintain lower heating costs for tenants. Thank you

If it's me and I want a maintenance free and paint free exterior...600 series with the capping done. Capping just the sills is silly and a recipe for disaster in my opinion.

The Okna window, capped, is the best product and value going on that list.

The OKNA 600 is the best of the bunch. Sounds like there is elaborate historic like exterior window casings/millwork if multiple outfits aren't including the capping?

The 600 for sure. The capping really depends on the house . It can look odd on older homes when everything else is wood on the exterior. The capping of the sill only seems odd, but is not a recipe for disaster if done correctly. It can be recipe for disaster even if fully capped and always need to be done correctly as it is the fail safe.
