It is faster, smoother and much cheaper to take I-35 to OKC and I-44 to Missouri.
The road isn't exactly silk smooth, but much better than US-69, also better than the Indian Nation Turnpike - which gets expensive pulling a trailer or in a big motorhome.
I have driven many of the other roads, such as US-271 from Paris, TX to Fort Smith, AR - excellent road, but mostly two lane and somewhat twisty in the mountains.
