If it wasn't for them, followed by the Invaders, you wouldn't have the Avengers or many of the teams you see in Marvel comics today.
Current status at Marvel
After World War II, The All-winners Squad decided to fight injustices in America rather than going against enemies involving foreign countries. The All-Winners battled Adam-2, an android who built an army of robots set out to destroy the world. Later on they faced a villain named Future Man, a time traveler from the year 1,000,000 who hoped to destroy all of humanity in order to replace humans with his race so they could inhabit the Earth. The Squad also ends up going against She-Hulk who traveled back in time to help some gangsters to acquire the atomic bomb.
The Blonde Phantom and the Angel would join sometime after the war as well.
