He's not just defeating Kaguya's portals though. He's beating Kaguya's portals, movements, jutsu, plus Madara's movements and jutsu too. Double mangekyou Kamui is clearly on par with Sasuke's jutsu and FTG according to canon. And it doesn't just depend on the jutsu. You must also take into account the user. If someone like Raikage or the Juubi Jinchuuriki had Kamui he'd be so much more dangerous because his actual accelerated thought processes (not to mention his chakra pool) would allow him to activate the jutsu even faster.
