Pros

It deletes files much much faster than built in Windows file manager.

TeraCopy can automatically check/verify the copied files for errors, by calculating their CRC or other checksum/hash value.
Pro Seamless shell integration
Pro Skips badly copied files
TeraCopy skips badly copied files during the copying process, and then displays them at the end of the transfer "Verify" with checksum/hash, so you can see which files to re-copy. See also, OpenHashTab for Windows and DeadHash for Windows, Linux, Android.
Cons
Con Default installation options include adware
You can avoid this if you select your options carefully at installation time
Con Avast! Antivirus automatically deletes the installer because of the optional adware installer included in it
Con Sometimes clashes with 7 zip
From my experience, TeraCopy does not do well in conjunction with 7zips.
It seems to error on some systems when you do a drag-and-drop extract.
