I have to do a one time data transfer of a lot of data. Is it best just to use my mac and copy over using the finder or to use a backup solution like Carbon Copy Cloner?

I have to make sure that the transfer goes smoothly and the backup is not corrupt. But I have no need to do on-going backups I just need an exact copy of this data on another drive. I would like to verify that all the data made it over. Are there any advantages that something like Carbon Copy Cloner, Intego Backup Assistant, or other backup programs have over doing simple the copy application in OS X? If I do that- is there a simple way of verifying the files? It is a simple copy of a lot of data but in very few folders, so selecting it and copying it over is certainly an option.
