[MCU] Which timeline would be the least unpleasant to live in had one of the villains succeeded in their goal?

For example:.

If Obadiah Stane killed Tony Stark at the end of Iron Man 1, would the long term repercussions have been better or worse than if the Project Insight helicarriers had successfully launched during Winter Soldier? Or if Ronan the Accuser had killed the Guardians of the Galaxy and purged Xandar with the Power Stone? Or if Darren Cross had killed Scott Lang and sold Pym Particles to HYDRA? Or if Hela killed Thor and continued her conquest of the universe?

Which timeline in which the villain wins in an MCU film would be the LEAST bad?

*Spider-Man: Homecoming*. 

If Spider-Man hadn't stopped Toomes, he would've sold a few more weapons to street criminals in New York.  Maybe there would've been a few more robberies before the Avengers or SHIELD stepped in.
