GridView vs DataList vs Repeater vs ListView

Hello all, I have read some articles about this matter... and it seems that the Repeater is the one with best performance as explained in this other question: I know that the GridView is the heaviest of them all, and that it weights a lot in the ViewState.

Preferred implementation of '<' for multi-variable structures

Initially this may seem overly abstract or philosophical, but I am genuinely interested to see if someone has a convincing argument in favor of one implementation over the other.

Using combination of File Size and Hash value of only first 20KB of a file to detect duplicates?

A project I'm working on requires detection of duplicate files. Under normal circumstances I would simply compare the file bytes in blocks or hash value of the entire file contents.
