I like sodas that are off the beaten path, so my favorite is Belvoir Rose & Elderflower sparkling lemonade. It's the perfect summer treat after coming inside from the heat. It's fantastic even when it's watered down, or mixed into a cocktail, or if you add it to lemonade, but it's great just on its own. I love floral and herbal flavors and it's just lovely.

My other favorite would be Reed's Ginger Ale, one of the few ginger ales you can buy made with actual ginger. It comes in several "strengths" and I like them all.
