Windows Desktop Application Automation Using AutoIt

I've been using AutoHotkey as well as AutoIt in the past. If I need keyboard macro, I use AHK. But if I need automation that interacts with other apps, I use AutoIt. It's fairly easy to get started writing scripts, but I've never liked the language/syntax of either AHK or AutoIt. One thing I wish I could do this is to write everything in Python, Lua, etc...

We do a lot of UI automation for testing. I have played with AutoIt quite a but I found it pretty difficult to get scripts to run reliably on different machines. It's get for one offs though. It wouldn't hurt if you could use it as a library from C# code. Or is that possible? The built in language is not that great.

What about other automation solutions, like UIPath Studio (which has a free community edition)?

AutoIT can connect to the ActiveScripting (Windows Script Host) environment, which is great!

Does anyone know how this compares to Sikuli(x)?

How does this compare with AHK (AutoHotKey)?
