What I am confused about is that USF are often called the weakest faction by a large margin with OKW often being considered either to strong or just slightly above par...
Besides a few fanboys, next to nobody is calling them weak, because they aren't.
Difference though is their gameplay. If a game goes into later stages, they tax you with a lot of additional micro (in comparison to other factions), which makes them annoying to play.
If you can't handle the micro pressure, you gonna lose by default. If you can, you gonna feel like you lost, even if you win.
And OKW has been kinda (over-)nerfed patch by patch, but they still scale very nicely in team games with backup - thin line to balance here
just my 2 cents.
