My favorite ship is Tails X Amy... Yep. But why dude? It's simple guys.
I think Tails X Amy is a good ship, because let's think, did you see Sonic giving attention to Amy? Nope, but now you imagine Tails, every time that Amy go talk with Tails, he aways gives attetion to her. He (Tails) doesn't get out running / escaping of Amy like Sonic, no... He decides to talk with her and to listen her.
We know that Tails already saved Amy sometimes from Eggman (Or Robotnik), more times than Sonic in my opinion... Even in the comics they make a great pair, Tails and Amy are aways helping and thinking about each other when they are together and that's cute for me.
So yes, I think that Tails X Amy is a good ship.
