Yeah you can't go wrong with any of the flavors Sprecher puts out, it seems.
Orange Dream - Basically orange soda but absurdly creamy and has a solid taste that never seems to get old no matter how much you've had out of the bottle
Red Apple - Strong apple taste and fragrance, slightly tangy. Not as solid as the orange one but definitely good
Cream Soda - Extremely sweet. probably the smoothest cream soda I've ever had
Cherry Cranberry - Sweet, bitter, smooth, and surprisingly complex-tasting for a soda. This is definitely worth experiencing at least once.
