I voted Coke and other. I don't drink soda anymore due to diabetes, just Iced Tea. If there is a can or Coke or a can of Pepsi I would grab the Coke. But it doesn't matter. When I was drinking soda my choice was usually based on price. So Great Value Cola was what was in my fridge.
Based on taste, Shasta (which is what I grew up on) and RC are my favorites.
Believe it or not SODA BRAND being sold in our snack bar was one of the big annual issues we faced in the 6 years I was on the Little League Board of Directors. Soda companies have budgets to offer "Perks" to get you to switch to their product. All new fountain equipment was , of course, a part of every soda companies offer.
Pepsi was very big on offering to donate all the cups, and electronic scoreboards as incentives to switch. Three of the Leagues six fields have Pepsi electronic scoreboards.
Coke was big on giving away supplies......cases of baseballs....a couple pallets of "Play Ball" (a kitty litter type product to soak up water on wet infields).
Then one year, RC became the official soda of Little League baseball, so there was a little push from Little League to switch, but the $2,000 cash RC was offering made it a easy choice. Not sure RC was a fan favorite, but Coke and Pepsi couldn't match that cash offer.
Of course, Coke is the best seller, and in recent years Dr. Pepper has pushed Pepsi to third place in sales.
