Pre JYM vs Pre Kaged Comparison Which is the Better Formula

I am looking for a high quality fully dosed pre workout and I have narrowed it down to Pre JYM and Pre Kaged. Both of these seem to be very popular among the more serious lifters here in the UK. They both have large scoops and avoid proprietary blends which I really appreciate.

I am wondering which one actually provides the best results for strength and endurance. Jim Stoppani and Kris Gethin are both huge names in the industry so I trust their formulations. I am looking for something that has a good amount of creatine and betaine as well as the usual stimulants.

Which one do you prefer and why? I am specifically interested in how they compare in terms of focus and how long the energy lasts. I do not want to buy both if one is clearly superior to the other. Let me know your thoughts on these two heavy hitters!
