Recover My Files may be costly, but I liked its tunable scan function; its professional-level support for devices like RAID drives may come in handy. Remo Recover is functionally similar to Recover My Files, but it turned up a high number of false positives during testing.
The biggest surprise was how two of the best programs cost nothing to use. While PhotoRec was the least novice-friendly -- its text-only interface could scare off the uninitiated and its documentation is spotty -- it was also one of the most powerful. Recuva was likewise quite strong and wasn't lacking any functionality in its free version.
As a result, I recommend PhotoRec for tech-savvy users and Recuva for everyone else.
