I remember comparing AutoIt and AutoHotKey to pick which one to learn. The community being really open and seemingly twice as large at the time was why I selected AHK. Shame about the language syntax though, I still fight with it. But it is very powerful.
The syntax was one of the main reasons I chose AutoIt. For some reason I cannot stand the AHK syntax. For me personally it is hard to bring structure to an AHK code.
