I am biased, but I love Ragnarok. I have went through several tubs and I have a lot more in the cabinet. Definitely one of the best preworkout formulations to date IMO. A full serving of creatine, plus electrolytes, stimulants, volumizers, etc. I've never tried WTF, and I haven't really looked into the reviews. If you'd like for me to pull up some 'ROK reviews for future reference I could do that for you.
