Answer: It would definitely be different from what we recognize today
Explanation: the revolution of the 13 colonies basically started the united states, if the colonies decided to remain neutral they would have probably gained independence eventually, and they might even have merged with Canada in the time of their independence, in this case, it would still be an extremely alternate world from the world we know and love today, as the united states wouldn't be making any independent decisions anymore, and they would still be loyal to Britain and the queen.
