I agree with the way you separate “best-looking” from “best to own.” After trading skins for a while, I’ve found that liquidity is often more important than people realize. A skin can have an impressive pattern or rarity, but if the buyer pool is tiny, getting out at a fair price becomes the real problem.
Redline is a particularly good example. It may not have the visual impact of a Fire Serpent or Gold Arabesque, but the combination of recognizable design, reasonable wear expectations, and consistent demand makes it much easier to move. Vulcan is another strong choice, although I’m much more selective about float when buying one. For newer traders, I’d prioritize skins with established demand before chasing rare patterns or expensive crafts.
