Starbucks cold foam or its delicious sweet cream -- which should you choose? Well, it depends on what you're looking for as the two are quite different.

Cold Foam Days at Starbucks take place from May 7 through May 11. Rewards members in the U.S. or Canada can add cold foam to a cold beverage for free. Starbucks has a legion of dedicated fans out there who probably love and hate their relationship with the store in equal measure.

When it comes to iced drinks at Starbucks, there’s no shortage of tasty options. Purists swear by cold brew, iced coffee and frosty Americanos, while maximalists are likely of the Frappuccino persuasion.
