Hisense 55' Mini LED in 2026

Hello, Im looking to buy a 55' Hisense Mini LED TV. Here in Brazil the options are kinda limited, the prices are a mess and the TCL C6K got a ridiculous increase in price in the last few months; and the Hisense TVs are an affordable option.

However, I couldnt find reliable and detailed information on the difference between U6Q, U6N, U7Q and U7N.

At the same time I heard the U7 is supposed to be newer than the U6, on some reviews they also noted the U6 is actually still better...? Either way, the U6 to U7 is around a ~60 dollars increase in price. Not only that, I still dont get the main difference between the UxQ and UxN models. Both on websites and different youtube channels generally say different info.

For usage purposes, I mainly intend to use it for streaming services. For gaming, I only have a Switch and will eventually get a Switch 2, but I dont plan on getting a PS5, XBOX Series, nor on using it on my PC. I also plan on getting an extended warranty.

Considering they are relatively close in price range, which of the 4 models would be the best option?
