Everything you just said is wrong.
Cavill gets my vote as well, as do Ben Affleck, Jason Momoa, and Margot Robbie, whom you also arbitrarily excluded.

Hence why there's No MOS 2. No one attached to it. No script. No progress on it in 5 years. MOS only made about 40 Mil profit theatrically for WB (11% ROI), which is very disappointing for them. It was also divisive with critics and audiences.
Conversely, Ant-Man made 2.5 times that in profit, hence why Ant-Man gets a sequel and MOS does not.
You don't know how Hollywood business works.

Also, Affleck isn't the lead of a superhero franchise. Margot Robbie and Momoa aren't leads of superhero franchises yet either, so that's why they were excluded. Will Smith is the top billed lead for the Suicide Squad franchise.
