The problem with ameno is that:


 * 1) 1.It has limited range


 * 1) 2.It is quite costly. Sasuke can use it like 3 times and then he shuts his rinneegan and EMS down for a while. And also he doesn`t use teleportations back-to-back, so probably ameno also requires a short cool down after usage.

But unlike hiraijin for example, ameno doesn`t require prep time.And also being able to shift virtually anything in space is pretty OP. I also speculate that Sasuke`s space-time portal he uses to travel through dimensions is also a form of ameno.
