I absolutely adore Kaladin but his chapters can be quite intense. Shallan's chapters, especially in WoK were very refreshing. My favourite PoVs though were the interlude characters: every single one of them were so interesting: Ishikk, Rysn, Axies, Ym (sniffles, salutes), Kaza (salutes), Ellista, Geranid (and her companion Ashir), Baxil (but really Ax and Ash), Sheler (so cathartic! Plus the General and the Hog).
