Other because all soda is good soda. Sure I have some favorites over others, but it is always good to switch up the flavors so you don't get too bored :3
Coke tastes okay if you're drinking the entire thing in one go but it goes from ice cold and tasty to flat and room temperature faster than you can go in for a second sip. Throwback (both the Pepsi and the Mountain Dew varieties) don't seem to go warm or flat nearly as fast, probably since it is sweetened with sugar instead of drowned in syrup, though regular Pepsi and Dew suffer from the same thing Coke suffers from. That corn syrup [bleep] isn't as good as cane sugar
I generally prefer Rockstar if I'm drinking something sugary and carbonated though I don't know if that's considered traditional soda -- in spite of the relatively low caffeine amounts for an energy drink -- otherwise I stick to my routine of 'waking up to a mocha in the morning and drinking water/gatorade, watermelon Arizona or milk the rest of the day'
