My fav thing is two things.

1. It reuses MY OWN CODE STYLE. So if I ignore a suggestion and setup a try catch in my own quriky way it'll actually reuse it later on when I'm scripting. This works best when you add comments for the sections you write FIRST. So you comment # create array for x data it'll do that or try catch for query it'll give you a suggestion for the next block right away.

2. DEBUGGING. github copilot can see your terminal and script so it'll give you a detailed breakdown and suggestions. Blew my mind the first time.
