[MCU] Instead of always transforming into the green Hulk, Banner always transforms into the gray hulk. How does this change things?

The gray Hulk has super strength, though not as much as the green Hulk, and human intelligence, though not as much as Banner.

He is also a thoughtless, selfish criminal with next to no empathy or remorse. Interests include wearing nice suits, driving cars, wielding weapons, putting down others to make himself feel better, and general lack of manners or morals. He hates Banner.

You're speaking specifically of Joe Fixit, one of the incarnations of Grey hulk. If he never became Green Hulk, and only ever became Grey, we'd likely never know about him as no one would be after him.
