俊 (jùn) describes a refined, elegant handsomeness, typically of a man, and is more formal and literary than 帅 (shuài) or 好看 (hǎo kàn). While 帅 is the everyday word for 'handsome' or 'cool', 俊 carries an older, cultured nuance often found in writing or historical descriptions. 俊 can also mean 'talented, outstanding' in formal contexts, as in 俊才 (jùncái 'outstanding talent').
