It's an opinion.
Basically, it's more or less a preference thing.
Personally, I dislike light phones. I had a Moto Z for the past year (replaced by the Note8 last September) and one of the things I disliked was the lack of weight. Without a battery mod on it, it felt way too light for me. I understand that for some, light means premium, but it's the opposite for me. Anything light feels too much like a toy in my personal view.
I preferred the near-200g heft of the Note8 (now even more so due to me slapping a thick case over it). Does it make it more "premium"? Heck no, but the additional heft makes it feel much more reassuring in my hand, like it's a solid chunk of slab.
