I know we've bickered about this too many times as it is, but Puncher, please consider that the notion of subjectivity isn't trying to debunk the notion of objectivity. The two concepts aren't just compatible, they're complimentary.
A person could acknowledge Jane Austen as a technical master of literature, without thinking highly of her miniaturist content. In contrast, another person could love Charles Dickens' large scale, dramatic stories while not liking how quickly he stoops to caricature. Our reactions to stories and art are more complicated than good vs bad.
You know, I actually agree with your first sentiment, for the simple reason it provides a practical and useful result and I am ultimately concerned with practicality.
But your second one is nothing more than applying subjectivity to some areas and objectivity to others. It does nothing to challenge the notion that one particular area is subjective or objective or neither.
Besides, is this even an issue of subjectivity at all? Does subjectivity demand an equal or proportional distribution of opinion?
Yeah hug and make up!
I guess it would have to be an e-hug 
Anyway, with you both going back and forth I'm going to use an example in music (since this is an OST thread after all) to illustrate reactions being complicated but still in a sense being "good or bad."
For example, you can appreciate Bach’s tremendous mastery over form and technical expression in many works despite them also feeling somewhat dry in substance at times, in lets say the Well Tempered Clavier. You can also like Vivaldi’s strikingly sensual and immediate appeal to emotion and natural color in the Four Seasons despite the relatively simpler stylistic impression.
But if you wanted to say who ultimately created the most powerful effect overall (combining an intuition for structure with great natural color), then you would arrive at Mozart who can appear rather sensual and soft on the surface but marries that softness to a powerful form and structure that isn’t always immediately apparent to consistently create those powerful effects, such as in the Vesperae Solennes de Confessore.
Also "Normandy" was a song from ME1 that was pretty cool, wish there had been more of that style in 3. I read he did the Red Orchestra 2 OST in some part which seemed quite good.
