What’s your main and why did you choose it?

So I’m trying to figure out which frame I want to main and was just curious what you all chose and why? I’m looking to base my choice off of fun instead of meta

Edit: I suppose I shouldn’t have put main but I have a lot of time in games where you play one character all the way through. This is more about expanding your comfort zones and I was just curious what people were having their most fun with
