Pro Excellent performance
Because it loads the whole file into RAM, replacing all string occurences in 100MB+ files is quick and easy. Every other editor sort of died during that.
Con GVim, like Vim, has a difficult learning curve
A lot of time is needed to learn all the commands and modes supported. A lot of time will also be spent tuning all the settings to the user's preference.
