I am probably qualified to comment on this as I moved to the greater DC area from Western Europe 6 months ago. There are pros and cons to both sides.
American culture is more politically extreme than European culture. Feminist activists, abortion activists, BLM and pretty much every other group is far more active in US than Europe by magnitudes. Everyone has their opinion and believes you need to hear it.
There is a level of aggression in America that doesn't exist in Europe. USA is a winner take all society where most folks are losers. This brings out the worst in people. People are stressed to the max, and inflation is only exacerbating this. Lots of folks seem ready to fight if you look at them the wrong way. As a precaution I've stepped up how I arm myself as well as prepping for physical altercations when not armed (BJJ, Striking classes). People in Europe are just more...calm.
In Europe, we were in an extremely conservative Bishopric, and more times than not our child was the only one in our Church. Families do show up for major holidays, baptisms and first communions but that is about it. The board of baptisms and funerals was telling. There were more immigrant kids on that board than native born, and more deaths than births overall. We only found lots of kids at the FSSP parish, but folks are far more insular than US. They don't generally accept newcomers and making connections was difficult. This would present problems with my child as she aged into her teen years. Meanwhile, we have an active conservative parish here with parallel organizations (American Heritage Girls, for example) that provide based connections for kids growing up. Free range children in Europe is accepted, where that will get you thrown in jail in USA. I believe firmly this is a huge impact on how kids see the world as they age. Dating is far easier in Europe than USA (I never needed to as I am married but anecdotal interactions and second hand stories from friends are my sources on this).
I am in arguably a fairly liberal American area and yet am not choked off by it. Even in California, 40% of people vote Red. I have come to believe (as a Catholic) that the quality of your bishop will impact your experience. Ours in here in the DC Area (not Wilton Gregory, the other one) is a very solid one, producing a large number of seminarians.
I miss Europe, and think about it much. The first 3 months here were really difficult. I have the option to go back at any time however I am not sure I will though yet. The longer I stay in America the more comfortable I am becoming to the idea of staying.
