Still using Jimmy Joy ( finishing old version ) and at the same time using Huel for lunch. Jimmy Joy taste is nicer but, when choosing the best nutrition, IMHO, the little more expensive Huel wins because I like the macros most:
More protein ( vegan sourced, that balances the risks of higher protein intake - different from the body reaction to non vegan proteins);
No fluoride ( When bought Jimmy Joy did not saw this. Now for me it´s a no go);
Clearer, simpler and more detailed ingredients proportions than Jimmy Joy ( in the later I cannot see by the label the proportions of each ingredients that give the final protein value ( soy vs oats since in this last version whey was removed) nor even the percentage in carbs of maltodextrin used. In comparison Huel doesn´t use maltodextrin ( except as a carrier in the flavourings ) and Queal ( another brand ) on their site are very detailed in all the proportions of each ingredient ( and with time they removed fluoride);
More than 70% of vitamins/minerals from Huel come from the food/ingredients in their natural form ( In Jimmy Joy I don´t know);
Buying in bulk quantities Huel pricing approach the Jimmy Joy princing ( even if Huel is more expensive 10/20% for me I´m paying something else);
More interesting 500 Kcal per meal approach ( for me 400 Kcal is a weaker measure ) with the number of meals clearly mentioned when you´re shopping.
Bigger bags ( easier to scoop and best for the environment)
Free shipping from 50€ to my country ( Jimmy Joy only from 100€)
Those were my main reasons for the transition into Huel, that I´m going into definitely.
Each product/brand have their believers and market. I entered the “lents” with Jimmy Joy but after research and my specific needs felt Huel fits my daily life better ( 3 X 500 Kcal Huel shake meals during day and one regular meal at night). Hope my opinion helps someone.
