Agree with Kirk, Single shot HDR ( pseudo HDR) are never going to compete with a bracketed set. I have never understood why so many people don't bracket as once set up on a custom setting it is quick n easy.
Most modern sensors do a pretty decent job of capturing about 10EV of useful DR. Most of the time, one can get away with 2 shots spaced 2 EV apart to capture the DR of most scenes. Used to be that at least 3 images were needed, perhaps sometimes 5 or more, and the EV interval had to be small (1 EV) to get the tonal transition and color correct.
When your metering tells you that you will need more than one exposure, it it super simple to acquire the sequence, even handheld.
Also, there are more options for combining the exposures, one being using PS/ACR to generate a DNG and tone it in ACR. No more need for the traditional 5 image HDR merge to a 32bit file, etc. if an LDR is your immediate final destination. That said, there are also much more accessible and powerful 32bit tools for using a 32bit workflow until the final reduction to LDR (for compositing, 3D modeling and image-based lighting, etc).
