I hear you. I’d definitely put Taemin in that list - because he continues to do some really different things and push the boundaries of Kpop.
I didn’t personally care for Suho’s music but it was certainly well crafted.
Kai and Baekhyun definitely brought some exceptional no skip albums. Baek being the consummate all rounder performer and delivering some gorgeous modern melange of r&b, Lo-fi and jazz, while Jongin really applied his emphasis on artistry to the visual aspect of videos and performances in a really unique way, while working on his honing his vocals for a strong delivery.
