@Stahesh @Tfmonkey I personally prefer Guarana, not in the form of an energy drink though. Just the one marketed as a normal drink.

What I like about it is that, while coffee gives a huge but short bust of energy that makes you want to drink more coffee once it's over so as to not be tired again, guarana instead gives you a small but long lasting increase in energy, which is better for long work hours.

It also has another benefits: https://www.healthline.com/nutrition/guarana-benefits
