When and Why Should I Use TStringBuilder?

Question

I converted my program from Delphi 4 to Delphi 2009 a year ago, mainly to make the jump to Unicode, but also to gain the benefits of all those years of Delphi improvements.<

Answer 1

According to Marco Cantu not for speed, but you might get cleaner code and better code compatibility with .Net. Here (and some corrections here) another speed test with TStringBuilder not being faster.
