that's true acutally. Priyanka has always been growing as an actor with each film she does. I haven't watched all of her movies but only Aitraaz, Anjaana Anjaani, 7 Khoon Maaf (which I only watched because of the title and how PC would play this character), parts of Krish, Andaaz, Mujhse Shaadi Karogi, Waqt, Barsaat, and Aapki Khaatir and I liked most of these performances of hers.
With PC, there is always growth and maturity in her acting; although, I haven't yet watched Barfi so can't comment on that. But PC sure has been improving with each movie.
Vidya, I feel, is the same from her first film - an amazing actor but I haven't seen any growth in her but then I only watched Piyu Bole movie and Kahaani so what do I know?
Kareena is also improving as well but only now in the past few years whereas PC has been since the start of her career.
Parineeti, I feel, is sort of same as PC. They both have amazing screen presence.
