[Sasuke Uchiha]

Well i have a better theory, it depends on how you use it i mean if you were to crash a rasenga with a chidori, chidori is history but chidori can be use more effectebly and dangerous like the way Sasuke uses it unlike suicide rasenge. I would rather like to posses chidori than rasenga, unless naruto do something than odama rasenga or the other powerfull suicide rasenga.
