It's questionable if base ISO DR is important to someone or not but it's very nice if you have it. Also there are some users like landscape photographers who benefits from sensor like in D600 or D800, they are more desirable for tone mapping than say a 6D sensor. All APS-C or FF sensor designers have better base ISO DR than Canon and it's price Canon is paying because of outdated FAB process which deny a possibility to put column parallel ADC on sensor. Right now theht is not Sony, Nikon or Canon who has the best sensor, it's Toshiba with sensor in Nikon D5200. Characteristics are just amazing, high base ISO DR and record breaking DR for APS-C sensors on high ISO which is according to DxO even on par with D600 Sony FF sensor. DR on high ISO is very important because not only SNR have a impact on apparent noise in on high ISO. It's almost one stop better than D5100/D7000 sensors on high ISO so it's a kind of revolution. I only can hope that Nikon will soon introduce FF model with Toshiba sensor.
