This depends on your definition of "friendly". Although there was plenty of animosity in the years after the war, Americans and British maintained a fairly cordial relationship because it was in the best interest of both countries to trade with one another. However tensions over land disputes and the British taking American sailors eventually led to the War of 1812.
Hamilton was seen as a person who favored more power obtained by the central government. This means he was in favor of things like a national bank, less state rights, and less of an ability for freed slaves to vote (because federalists were also democrats). Jefferson, on the contrary, was an anti-federalist. He feared that excess central power would infringe on the rights of the states, and so to avoid this, he did as much as he could to retain state rights. He also believed central government authority gave more power to the upper class (wealthy whites) than it did to the common man (poor whites, freed slaves).
