How is Apple a monopoly?
You could argue I'm just saying they're high quality, which may be true, but the software has been degrading and I have no options if I value openness _and_ quality.
I can flip it and mention features that Apple products don't have that I like.
But this isn't actually an argument for monopoly. That just an argument that you like a company more then the other.
Anticompetitive market structure is bad for consumers loooong before it results in an actual literal "only one company in a broadly defined niche" monopoly.
