Obito is the very definition of greater than the 9 tails even at that young age. As you noted he controlled the 9 tails with genjutsu. To be able to control something completely is the very definition of greater as he completely dominated the 9 tails with Genjutsu. If you're going to discount this then you might as well discount Itachi entirely as his power is primarily from Genjutsu. He might not be equivalent in power in every area with the 9 tails(such as scale of destructive power in Ninjutsu) but to completely control something as I just noted is the very definition of superior.

So you honestly think if Obito fought Kurama one on one without Genjustu, he would win? No, because genjustu is different from being stronger. Itachi was proficient in genjutsu because he was a pacifist, and didnt have much chakra. So once again, Obito isn't stronger than the Nine Tails. Also, Minato was Obitos master, Obito knows a lot about him and still lost. Kamui is better than FTG, but Minato is smarter and more experienced,as well as stronger. Minato took on the Nine Tails himself and won, kinda
