BSN also makes a protein powder called lean dessert protein (LDP) that is lower in fat and carbs and it is delicious. There is not cookies and cream though, the vanilla, chocolate fudge puddinng, and chocolate coconut candy are really good.
The ON protein you were looking at I believe is 100% whey while the Syntha-6 and LDP are protein blends. You probably prefer the taste of blends.
Remember to look at serving size as well, for Syntha-6 they report a 44g serving, LDP is 35g, and ON is 32g. They always give the same scoop size!
Dymatize Elite Gourmet Proteins are pretty good too, they are blends and there are a lot of flavors to choose from.
