Unfortunately due to work I'll have to abandon my lovely Mac system. Keyboard Maestro is a core part of my workflow though, 90%, so I'm desperate trying to find a replacement for this amazing app.
Do you guys recommend anything that would come close in terms of ease of use, functionality, GUI?
I cannot stand AHK after I've been using KM for several years 
I know this question has been asked but it was quite some time ago. Maybe I'm lucky?
The options are mostly fairly scripty I think โ AutoIt seems slightly preferred to AutoHotKey now.
I use Fastkeys, see https://fastkeysautomation.com/index.html
Although not comparable with Keyboard Maestro.
Actiona is a task automation tool. It allows you to create and execute action lists. You don't need to know any programming language to use it: its intuitive interface allows you to create action lists (scripts) using drag & drop. Advanced users can use JavaScript (EcmaScript) to extend its functionality.

I am not leaving apple but I have a Windows PC and wonder weather there are news on the matter. Thank you.
As far as I know many use AutoHotkey.
Microsoft Power Automate is another option.
I stumbled on Power Automate over a year ago. But since I am on a Mac, I was searching for an alternative to it. That was how I found out about Keyboard Maestro. I love Keyboard Maestro so much. 
Actiona: Well that does indeed look very much like Keyboard Maestro's actions ...
Any news on this subject? I also have to use Windows at work and would like something similar to Keyboard Maestro.
Did any of you try out either Actiona, Autoit or MS Power Automate?
If so what was your experience?
