What I (still) might suggest you do before switching software in search of a magic bullet is to think about what's lacking in the scan and how it might be tweaked to get some better results.
Is it blurry? Poor highlight or shadow detail? Colors off? Or maybe does it just lack punch or look blaaah?
I have yet to find a properly-exposed C41 (or c22 or slide, actually) negative that it can't make a good scan of*, and I've scanned all kinds of various films from Fuji (mostly), Kodak, Agfa, even Ferrania, and even some 30 year old Kodacolor II.
A couple hints I might give you: If you want a good print, scan at maximum resolution, 16 bit, multiple passes. I use 4 passes for those I want a good print of. Adjust levels only in the scanner software. Use Photoshop or whatever to do any correction, sharpening, tweaking, etc. and of course touching up.
If the negative or slide is not reasonably flat (more with slides than with negs) help the auto-focus do its thing. I've found the auto dust brush is a placebo. I use canned air (yeah, I can hear the booos coming from the peanut gallery) to get rid of any loose dust, and in cases of really grody negatives, filtered H2O, rubbing alcohol, or film cleaner.
I've really had good luck with this thing.
* I do have a few available/low light Walgreens/Agfa negatives that I cannot get a good scan of. However, the scanner does better (less worse?) than the minilab scans. There are exposure and color balance issues here.
