@FLatzone, he never said the Sage Mode itself was weak, and he never implied it either. The only thing he did was begin to ask a question, which could have easily been "Sensei, your senjutsu... it doesn't last long does it?"

Minato says he's not good at Sage Mode, and explains it takes him too long to enter Sage Mode and he can't maintain it long. So he literally explained that the reasons why he was bad at Sage Mode was because he took too long to enter it and couldn't maintain the mode very long. He didn't say his Sage Mode was weaker in strength.

Nowhere does this imply that his Sage Mode is weak. In fact, the rings around his eyes imply it gives the same boost it gives to Naruto, but he can only last a few seconds in Sage Mode.

So no, no one confirmed it was weak, you're again pulling incorrect facts from texts that don't imply what you're saying. You just want to downplay Minato every chance you get, and it shows lol
