I ran a quickie comparison test between my FF K1 + 31mm ltd lens and my SDQ + 18-35mm A lens set to approx same 31mm focal range as my Pentax lens. Same aperture, same tripod no sharpening but images adjusted for brightness. There was little difference generally but I thought that the SDQ images were a little sharper. Don't forget that the Pentax is FF and the 31mm is one of Pentax's best lens! I use the Pentax as an alternative when conditions or subject matter does not favour the Sigma. Both systems are excellent at what they are designed for. I suspect that my post may not clarify your dilemma but in reality I get more satisfaction from my Sigma. I do not find that the DR is much of a problem.

Wow, you're right - this does not help me at all! I much prefer the SDQ photos above to the K1 except for maybe the twine, but that had more to do with exposure. And, the K1 is full frame, with the Holy Grail of prime lenses. This says a lot for the SDQ. Hmm.

Wouldn't a full frame Foveon be amazing!?

Not having a big DR is annoying, but it can be overcome. Use SFD mode and play with the raw image. If there is wind, use a graduated nd filter. It makes post processing much easier, and with less HD artifacts from overdoing SPP sliders. Just make sure to buy a good quality filter, not the el-cheapo ones. Is it more fiddley? Yes. But it makes you slow down and THINK about what you are DOING, and why which is better. On each shot, I set the white balance in the camera using settings, or manual white balance using a card. It made a big difference with the final good color quality. I always carry a light travel tripod to use for SFD mode if the situation calls for it. Slower work is better.
