Multi Shadow Clones and the Reasengan both have a very basic similarity which makes them Naruto's signature techniques. Rasenshuriken isn't his signature which I explain below. Naruto is the only one who can use them EFFECTIVELY! Others can use Multi Shadow Clones but the chakra is split so thin that the clones can't do much past taijutsu. Naruto can actually make a bunch of clones and have them use ninjutsu themselves, plus a lot of other things. This makes it Naruto's signature Pre Jiraya training.

Then once Jiraya trains Naruto he learns the Rasengan. Again Naruto is the only one who could use this technique as intended. Jiraya can make a rasengan but he doesn't use it much in combat as he has other techniques he relies on. Kakashi has his lightning cutter and those variants. Minato died in the main series so I am not including dead shinobi or those who were reincarnated during the war. Plus his signature is FTG, not so much the rasengan. He got his nickname BECAUSE of the FTG. The rasengan "replaces" Mutlti Shadow Clone as Naruto's signature as we see in all of part 2 he makes more and more variants. He also slowly starts using Multi Shadow Clones as utility and distractions in battle instead of a full on offensive attack.

In my opinion the ultimate variant of the rasengan not using any kind of mode like KCM/ SP/ Sage Mode is the Rasenshuriken. Adding a nature element is common in many techniques and many shinobi can learn that element but NO ONE can learn how to do the Rasenshuriken. I still think the Rasengan is Naruto's signature because it's still his most used, fastest, and he can do more with it. By the end of the 4th Shinobi War he can create it in one hand without clones. He still needs clones or chakra hands for the rasenshuriken. In his fight with the 3rd Raikage which technique does he use to defeat him? The rasengan, not rasenshuriken. Just like what you all were saying about rasenshuriken vs TBB is true with rasengan vs rasenshuriken. Naruto has more control with rasengan and can pinpoint the place he wants to hit.

This strongest technique is signature technique is incorrect. Signature means the technique a shinobi uses the most and is unique to that user. Like I said above, Naruto is the only shinobi that uses both Multi Shadow Clones and the Rasengan effectively and consistently. Naruto's strongest is of course the TBB and those variants which includes Tailed Beast Ball Rasenshuriken.
