lol hmmm .... not really sure (altough people always reffered to ftg as the forth's jutsu), but am sure about two things :
1. the second's ability probably gave minato the idea (inspired) so the second used a DIFFERENT concept of s/t.
2. minato is by far better at it since s/t (space time ninjustu) is what defines him, he is a master of s/t.
you really don't consider teleporting as speed ??

its all a matter of how you view it bro (i respect your view), but i also have my opinion witch is who was the fastest from point A to point B no matter how he got there. its also kind of cooler that it was teleporting and not just moving, its instant (now thats fast xd)
