I don't love it, I don't hate it, and I'm glad I got it on sale. For the price, even at full price, you really can't go wrong though. I never had actual Rockman hardware unit to compare it to, so I can't say how it compares to the real thing.
In general, the presets are few and they didn't blow me away. But there *were* a couple of good clean sounds. The good news is, I think if you spend some time tweaking it, you can get some good sounds, and there aren't thousands of options for reverb, delay, etc. that could confound you with option paralysis.
There's a trial. I recommend it before buying anything.
