It's unfortunate that in the final results the three images are completely different:
- the luminance result is unwhitebalanced, it looks nice but people may complain it's too yellow
- the hugin result needs to be cropped, and is projected, vs. plainly mapped. That's OK for stitching a panorama, but something you wouldn't do if you used a tripod and do not need aligning.
I use hugin and luminance myself, but often prefer to whitebalance manually before stacking and tonemapping, etc.. Luminance does an excellent job for me as part of the processing flow, emphasis "part".
