I think in the end you might find there are far more similarities than differences in Steves, and that some of the differences come from what they and you have and haven't experienced. Actions and choices might have been different, but the heart of my Steve, you, and other Steves is still that of the best of men. But I'm extremely biased toward Steves in general, and critically biased against the Thor of my timeline, so you should take all of this with a grain of salt.
I was very lucky to have had all of them, believe me.
