Personally, I really enjoyed the Rocky Road UMP :P Actually tastes like Rocky Road to me.
I thought SAN Titanium chocolate graham cracker was just okay. I wouldn't buy it again. Vasolate is my fav choc protein but that's more of a before bedtime blend.
This stuff is awesome. I really love it. I use it all the time and make sure to stack it with something good too. It works by itself but it's better when stacked with something.
Ump and XF 2.0 are on a different level compared to others.
