Grayfia and Diehauser would still be more powerful, besides there's still guys like Tannin around.

Ise and Vali are still far from the top. They still can't maintain their full power beyond few minutes. Some may say they beat Rizevim and the two top Evil Dragons but there's a difference that people need to account.


 * 1) Rizevim was mentally exhausted due to Fafnir
 * 2) Apophis and Azi wanted to fight Ise and Vali head-on. It's like Ise vs Sairaorg in Volume 10.

Grayfia and Diehauser don't fight like the Evil Dragons or Rizevim, you can't put their fighting style as the same.
