I mean Homelander's powers would be excellent if I'm living in that universe. Lots of scary shit and people killing each other. Although if I have Homelander's powers, living in a world with Homelander, he probably going to try and kill me... Which isn't ideal.
In which case Soldier Boy's powers seem like a good choice. Which I'm largely picking so I don't get murdered by other superheroes.
I mean Ahsoka and Maul's stories continue in Rebels as a follow up from Clone Wars. I'm sure you could watch Rebels without having seen Clone Wars, but if you're going to watch Rebels I would highly recommend Clone Wars first.
