One airport I like to visit, (KSEZ), has significant runway slope. I will land uphill with up to a 10 kt tailwind and need less runway than landing into wind. It is normal practice at this airport to land uphill and takeoff downhill and most pilots adapt to the fact that the single runway is simultaneously active in both directions. A Phenom pilot who thought one must land into the wind went off the end, through the fence, and part way down the hill.
Slope can be more important than wind direction in deciding best landing direction.
