And yet if your statement were true, it would not explain why others who also own "both" disagree with you. Absolutism does not serve you, there are few subjects in this world that lack nuance.
I'm not sure how that implicitly conveys an opinion.
Saying "the sky is blue" is not an opinion when the sky is blue, it's a fact. Saying something is better is also not an opinion, it's a fact. Saying "in my opinion" or "I believe/think/feel like/etc" makes your statement an opinion, ommiting that is ambiguous and is left for interpretation.
