I can argue that base Naruto cant beat Neji, Kakashi, and Sai. Not so sure about Asuma, but he could give him a run for his money.Base Naruto is most definetely very high jounin level just like base Sasuke (3 tomoe only without CS and without Oro's powers). Remember base Naruto and base Sasuke are equal so we can bring in Sasuke's feats to hype Naruto's level as well. Some people underrate base Naruto but he can beat most jounin level ninjas in this manga by overwhelming them with shadow clones and rasengan. His speed and taijutsu skills have also improved quite a bit since the beginning of Shippuden. He also has summons which allow him to overwhelm the enemy with fire power.
Naruto is almost jounin level when it comes to battle smarts so people should give him a break when it comes to his intelligence, it is good enough.
Let me put it in perspective: base Naruto can beat: Asuma, Sai, Neji, part 1 Kakashi and some others.
Both Naruto and Sasuke can challenge some low kage tiered ninjas in base but they will ultimately lose most of the time.
Naruto doesn't display jounin-like intellect on a regular basis. Just because he showed some great strategical planning and creativity a few times doesn't mean that he has jounin level intellect.
As far as Naruto being as strong as Sasuke, its in terms of power. Naruto pretty much outclasses everyone when it comes to power. However, his slightly above average intellect keeps him from advancing further in the ranks. There is only so much that raw power can do.
