Up to a couple of years ago, most Asian shops around Birmingham preferred Red potatoes - Romano,Desiree & Mozart. Two years ago there was a massive shortage with very high prices, a lot of shops switched to White potatoes - Melody, Estima and Harmony mainly because they were a bit cheaper. The same is true today.
Romano and Mozart have a higher dry matter content than say nadine and harmony.
This makes them more "floury". They take longer to cook through, but they dont start disintegrating quite as quickly. That makes them good for things like stews and casseroles...and Bombay Aloo.
Just my opinion - thats all.
