Data Recovery apps??

[The_Prodigy1982]

Hi Guys,
I could use some advise... so far LUCKILY I never needed it, but better be safe than sorry I guess.
In case I accidentally delete certain important files, and I want to be able to recover them, what apps are the best for this task?

For example:
• Data Rescue
• Disk Drill
... or any other?

If you have any recommendations, please also tell me why you would opt for that certain app?
Thanks in advance...
