Fruity Cereal proteins:
MAN is releasing one,
Performix has one (that is good),
MSI Lean Charms is solid,
1st Phorm is ok, would never buy a tub (Glad I got a sample)
CTD Sports is artificial,
Merica Labs has one (Tons of marshmallow mix-ins) have not tried, but I saw a buddy of mine said it was good but Performix was better.
As far as ghost flavors:
Best blueberry out (IMO)
PB / Cereal Milk (both top tier)
While their chocolate is ok, it is still much better then 90% of the others out on the market.
I assure you snickerdoodle won't let you down. I am going to request that flavor from Dan since he is sending me a tub shortly. Ill make sure I compare to the other brands you mentioned (MTS/PES) I personally find MTS the best snickerdoodle on the market as well.
