I just purchased Sharpeye 2.61 and am using Finale 2005b. I also still use Finale 2003a and it works with it also. I purchased Sharpeye because the included Smartscore lite was poor compared to the one included in Finale 2003a. Sharpeye actually works and I am able to move a good number of scans over to Finale without much clean up if the original is formatted to common standards and it is a clean scan. Sharpeye does an impressive job recognizing notes and fair on text and lyrics. I save as MusicXML which can be read in Finale through the MusicXML import.
Sorry, I can't speak of the other programs but if they have the Recordare MusicXML plugin included they will read it in. This is the only translation format besides midi (poor, last resort) that I know works with Finale. I am not aware that it can import from NIFF or the native Sharpeye file format.
