Given that the sensor in the 420 is 44% more sensitive and there's theoretically at most 33% more read noise, seems your SNR and thus dynamic range would be better with the 420. The other question is how often are you shooting such that you'd actually be read noise limited? You should be aiming to avoid that anyway.
