i'm a bit confused? Better in Chakra Transfer? iirc, Chakra Transfer is a skill which allows you to transfer your chakra to another individual.. what Sakura is doing now, and what Tsunade did during Pain's Attack is called Remote Healing.. Such feat takes a lot of chakra and skill healing many individuals simultaneously.. Sakura is currently healing of what remains of the Ninja Alliance.. if we would remember, before the Juubi appeared, the Alliance (which originally had 80,000 people) has already loss half of their people which is about 40,000 people.. When Madara summoned those 2 meteors, only a handful survived the assault.. since then, there had been more casualties so we can assume that there are currently probably about 10,000-20,000 people.. but we don't know, how many of them are currently being healed by Sakura.. on the other hand, Tsunade healed every person inside Konoha during Pain's attack.. she healed them using her own chakra pool over extended periods of time.. when Pain used Shinra Tensei, Tsunade only had nanoseconds to counter it.. her only option is to release her yin seal and pour all the chakra there so that she can protect EVERYONE, and when i say EVERYONE, it includes those who were alive and DEAD.. now, the only way Sakura can compare to that is if she can protect everyone in the alliance (alive and dead) when the Juubi uses an attack that can destroy the entire battlefield simultaneously..
