Quite true as naruto trained intensively whilst Sasuke got his power ups mainly through his sharing an almost every time he felt a little sad. But to be fair Sasuke did train with oro albeit with a little help from drugs
Sasuke got too much freebies. Curse mark is a freebie that required some of Sasuke's cry drops and pain screams, MS/EMS was an upgrade given by a ill Itachi, and Amaterasu/Tsukiyomi (and genjutsus) were techniques transferred by Itachi. Sasuke's enton control doesn't have any meaning without Itachi's will to protect Sasuke (no technique transferral = no amaterasu = no enton).
I won't bark about his first Sharingan levels since at least this is something he trained by himself (okay, Itachi and Naruto were the responsibles for his evolving).
The only achievement Sasuke got by training by himself was... what? Fire Release + Lightning release + Kenjutsu + Shuriken control, and that's all.
...in the other way, Naruto trained to have control over Kage Bunshin, Tajuu Kage Bunshin, Rasengan (+ amplifications or variations), Short-Range Rasen Shuriken, Sage Mode, Kyuubi Chakra Mode + Chakra Control (included Shunshin no Jutsu), and he invented the variation of Long-Range Rasen Shuriken thanks to Sage Mode learning. Plus Naruto is quite skilled with Kunai, pretty much he can deal quite a battle with Sasuke under balanced circumstances.
There is no powerup Naruto didn't need to master before using it (and no, Bijuu Mode is a variation of Kyuubi Chakra mode which needed training as well, so don't wank with this).
Sasuke got his way too easy. It's quite like I said earlier... he got too much sugar daddies, these are named Orochimaru, Juugo, and Itachi -_-.
or :nuts:
