The thing is, if you live in the west then all the other major Android brands aren't better at all. There just are no good options anymore. HTC went bust, OnePlus turned to shit, LG threw in the towel, Sony's SW updates cycle is unimpressive for how expensive they are, Google Pixels are buggy as hell and not available in every country, and Motorola, Nokia and Blackberry are basically rebadged Chinese OEM designs. This lack of good options explains why Android lost so much market share to iOS in the last years.
Excluding Chinese phone makers, Samsung is pretty much the only big player in town from a western aligned nation, that has its shit mostly together as of present, promising 5 years of updates, having service and distribution centers in most countries around the world and a wide portfolio covering all price brackets.
For example, if you're in the market for a new relatively affordable mid-range ~300 Euro phone, then Samsung is pretty much your safest bet in the Android space.
Sure, there are better option like Fairphone but those are far away from being globally mainstream.
