If the team is "boring", that is an issue with the writing, not the characters themselves.
Sonic and Tails, or Sonic and Amy, alone should be inherently dynamic and fun in some way. Obviously, the same should also apply for Tails and Amy, in an ideal world. And thus, having all three together should lead to more dynamism or whatever.
Between Sonic and Tails, the thing about Tails as "Kid Sonic" is that he's really an Anti/Nega-Sonic at his core, but that core is overwritten with the desire to instead be "Sonic" himself.
Anti Sonic is Knuckles. Nega Sonic is Blaze. Their fundamental core is "what Sonic is not". Knuckles is Sonic's antithesis, he is against Sonic. Put them in the same room, give them the same goal, and they will find a reason to fight each other instead because they just can't agree. Put Sonic & Blaze in the same room, and even if they don't fall into fighting each other the same way, there'll still be tension and conflict here regardless because they are fundamental opposites.
With Tails, he should resonate with Knuckles and Blaze in spirit as well. However, those same traits that give Knuckles and Blaze their strength, is what Tails should be insecure about. He doesn't have that faith in himself. Where Knuckles dislikes Sonic or can't stand him, Tails idolizes him, perhaps for all the same reasons in some inverse way. Just like Knuckles or Blaze, Tails IS NOT Sonic and yet he wants so desperately to be like him, he looks up to and admires him.
Tails will follow and trust Sonic, but because he ISN'T Sonic himself, he will not understand many things about Sonic or the choices that he makes. At least, at first. Meaning, where Sonic is a wild and chaotic cartoon character, Tails would likely be the straight man in any given scenario.
Tails is a kid who "wants" to be like Sonic, but isn't. And if/when he grows beyond Sonic, he will blend Sonic and Anti-Sonic traits together into one hybrid concept.
