Ok I'm a long time Photomatix user, but after reading all the great reviews i had to try it.
Its interface is great, quick, easy to use, its pretty much self explanatory.
In use however, I'm finding a lot more noise than I'm used to in Photomatix. Also the ghosting doesn't work quite as well as Photomatix either.
The best thing so far about it is its so versatile. If you have a certain way in your mind you want your image to look like this program can do it, but If you stray just a bit far from normal, you'll encounter noise, and lots of it. Not nasty huge issues, just lots of fine noise, most of which yu can get rid of with a good noise reduction program. The Upoint control is pretty cool, but I do wish you could choose different shapes for the control area other than circles. maybe you can, I'm not sure yet as I haven't used the program very long.
