It doesn't matter where you live in the world, there will always be arguments about which countries, cities, hell, even towns, do things better.
The reality is every location has its pros and cons, and those largely hinge on what you want from life and where you live.
Jazz and smoked brisket.
The United States has the most robust national and state park system in the world.
Air-conditioning.
Handicap accessibility.
Create the conditions for Breaking Bad.

Cancer survival rates are higher in American than in Europe.
I think that the natural aspect puts up a fight. I lived in Europe and the US, so it's hard for me to pick. I think the US obviously has more diverse landscapes. Desert, mountains, cold, hot, almost tropical beaches as well as icy cold ones.
And it's all one country, so no borders or language barriers. But I will say Europe has WAY cooler historical sites. That and for me, I love cold weather, and I will say that Europe's cold natural areas are stunningly gorgeous.
Legalization of cannabis.
Space. Both in terms of exploring outer space as well as just having more of it (i.e. more sqft/meters in US houses, bigger vehicles, roads, etc.)
Win the world series. The US is 116 - 2 (Toronto has won two world series). Europe has won a big ol' goose egg. /s.
I can only speak from my personal experience and that of acquaintances, but I am inclined to say diversity and racial sensitivity.
I constantly hear Europeans thump their chest and boast about how they “don’t see color,” but this was certainly not my experience as a biracial woman. I visited Greece with my mom and aunts (they’re all black) a few years back.
We had locals make monkey noises at us and our tour guide told us that they were commenting about how “animal-like” we looked. It was incredibly dehumanizing.
EU citizen here. I have some ideas.
Having an actual federal system (with all the advantages that come with like easier to travel between states, harmonized school system across states etc, organized research, etc)
A big art scene where they aren't afraid to explore their various cultural traits
Highly critical of their own society (which can lead to faster societal progress)
High defensive spending (which we really should do as a EU wide army if we want this achievable, not just individual nations)
Job opportunities: Wages in the United States are significantly higher than they are in most European Nations. (Note that labor laws could certainly use some work, however)
Small businesses: The barrier to entry for opening, incorporating and operating a small business is very low in the US.
The Small Business Administration also provides owner-operators with a plethora of resources, including low-interest rate loans that provide large segments of society with a path to opening their own business.
Moreover, tax schemes like pass-through taxation for LLC's and LLP's allows small business owners to avoid double taxation, and increases the odds that a new business will remain viable.
National Security: There is an effectively zero chance that the United States will ever suffer a real invasion. Unfortunately, as we have recently seen, this cannot be said for large swathes of Europe.
Street signs - in Europe they often just tack a small sign to the side of a building (if there's a sign at all); in the US signs are larger, close to the street (or above the street), and much more visible.
