Aijimu is hax to almost disgusting lengths, but she doesn't have a chance against all the Gold Saints. Waaay too much speed and power and their own fair share of hax.
True but the meteors are not huge by meteor standards. He can treat it like Jahuko Raikoben and dilate time to move away. A misconception is that he aged the blast. That wasn't the case as seen when he didn't age it the second time it was used. Of course he can age things away too but I don't see it working for something as massive and fast as a meteor.
