Which Latin American culture do you feel you understand and vibe with easily and with which are you like, huh, we don't share the same culture at all?

What do people think, which LatAm cultures seem more similar to yours, and which do you feel like are super different?

For me, child of someone who came from Paraguay to the US, and growing up in the midwest and E. Coast there, I feel I can easily understand or feel at home with Dominicans, Puerto Ricans, Brazilians, Colombians, Cubans, often Venezuelans or Hondureños, Nicaraguans, Panameños, Costa Ricans, and Paraguayans or Uruguayans. Somehow I feel like we have some similar ways of being. It's of course a gross generalization but I often find a similar way of sociability, friendliness, and keeping an upbeat/positive attitude.

Meanwhile I have lived in Mexico for almost 13 years and I <still<< feel like I don't understand the mainstream culture or feel understandable to people, I feel super super different here always. I think I understand some about Yucateco Maya culture, and can relate to it a little more, but mainstream culture, I am lost to this day.

Wondering where others have felt most and least "at home"/similar in Latin America, and what your home culture is?
