Help me choose a main

I was a gusion main for the most of my time but i think i need a change. I want a difficult hero to master which will be worth it and can make epic plays if i master it well. (Also they must be cool hehe)

I have these in mind but please suggest if you think others can be a good option.🙏🏼

Selena, benedetta, ling, lunox.

Note: I dont like how chou works also not a big fan of his sound effects else i would have added him here.
