If you would go for the numbers purely I think Paul, but I could be wrong.
I've also purchased Janka's product a while ago but I think Andy's style is way more 'effective' in the long run. Hereby I mean that Yad probably creates a more meaningful connection with the women in the long haul which resonates with me personally a bit more but I like how Janka truly tunes in to the very sexual nature of women. Both guys are my personal heros so I couldn't really pick one. They both have a completely different style and vibe, which shows that you shouldn't copy someone inch by inch but use their wisdom to create your personal style. Thinking in terms of 'who is better' is quite black and white imo and I think its a bit flawed. There is so much more to it like personal preferences regarding life style.
