Based only on color I'd go with the darker type. I like sweet potato
pie to have a color closer to pumpkin pie than to lemon pie.

Sometimes I think the yellow ones are more stringy than the orange ones.
I'm not sure if that's because they are smaller and thus less forgiving
of being orver cooked or under cooked so I cook them less. It sounds
like you cook them drier for a similar reason.
