Photomatix does HDR but also exposure blending. The "HS Adjust" method they have uses the same algoritms as enfuse, and will usually bring the most natural results.
I use exposure blending or HDR routinely for 360 panoramas, where the dynamic range of the full pano is way over the dynamic range of a DSLR. Jacques Joffre, the inventor of Photomatix is a talented panoramist, and created it out of his frustration with manually blending exposures in Photoshop (that was before CS2 of course).
Also, in real estate photography, exposure blending is usually required when there's a nice vista you want to show along with the interior - either that or spend 45mn adjusting strobes to light the room to the level of the outside without creating too many tell tales shadows.
