Yes, I also tried a few. But SmartScore Pro produces really good results (of 
course depending on the image resolution). If your imag has only four pixels 
or so between the lines of each staff (which means that the beams of the 16th 
notes are basically only one fat beam; I've tried such a piece more or less 
successfull), then you'll have to do a lot of editing, but with 300dpi I got 
really good results.

Note that for this you'll need a real PDF containing lines, curves, etc., not 
a PDF containing an image of the score!

Audiveris is the only usable open source OMR application that I know: 
https://audiveris.dev.java.net/

It still has it quirks and you'll have to do a fair amount of corrections, 
though.

Cheers,
