Savage World's newest Superpowered companion is what you want. It's a great middle point between something like Hero and something like ICONS.
My personal favorite Superhero system is Mutants and Masterminds 3rd edition, as I look at it as having all the granularity of Hero/Champions but with much easier math... But Savage Worlds Super Powered companion takes it a step further in terms of an easy to handle and fast system, while still giving you lots of customization.
