What about outlook? I never got on with it, but it's often considered the gold standard for calendar and task manager.

I use Outlook as my mail client on Windows and for that it is alright. I tried using it as my calendar and I am not satisfied with it. The UI looks ancient and it lacks a lot of modern features like natural language input.
