I think they're both fine honestly.
I really think the only reason you guys think this way about this kind of thing is because either you're young and haven't watched or read many shows before or you're just that easily turned off by repetitiveness I guess.
No disrespect to anyone's opinion, that's just mine. For me, I understand that signature moves are to be expected in action series like this. It's creates familiarity and distinction for characters. I've been watching various shows ever since I was a kid and it's the same thing for all of them. Pikachu's Thunderbolt, Goku's Kamehamehah, etc. That's just how it is. I guess after awhile you just stop looking at it as "boring" or not.
As for Naruto, there is a vast majority of moves, but few of them are honestly all that deep or intricate. You can name some with notable varieties compared to other jutsu, but it's all pretty straight forward stuff. Besides, if you add too many changes to something, eventually it will become something else altogether. If you didn't see Rasengan or Susanoo as often, chances are most of you would think they're cool and want to see more simply because it's not shown as much. If Naruto's special move was Mokuton instead of Rasengan, most of you would probably be over that by now too. To me, if your reason for them being "boring moves" is you don't like seeing it all the time, then the move itself might not be boring, you would just like to see other things is all
