It appears they were both started by the same engineer, Robert Simpson. Both are for SQLite 3. Simpson doesn’t appear to be active in either at this point.
Since they are both ADO interfaces, they should be quite similar. There may be minor issues in data compatibility because of peculiar behaviors in SQLite, and the way these ADO interface deal with them.
Since you state your platform is only Windows, I think System.Data.SQLite is likely a better choice, but it is likely a minor difference.
