What’s the coolest subclass

Hey!

What’s in your opinion the coolest subclass? I personally have only played Fiend and genie, but I’m curious to see how other people like the others. 

I know hexblade is best damage wise but is it as fun to role-play as the previous ones?

I currently play a Fathomless warlock and enjoy the action economy+features. Good field control in driving enemies back with Repelling Blast along with extra damage and 10ft speed reduction from the tentacle 

Love genie warlock, but van richten’s undead warlock was really fun.

Playing a game now with two warlocks in the party, One Hexblade (pact of Tome) and one archfey (pact of Chain). Both are great fun
