I searched but didn't find what I am looking for.

I would like to check out Destruction. Which post-Release From Agony albums do you think is best and second best?

Same for Kreator, which two post-Terrible Certainty albums do you recommend?

Looking for overall aggression with strong vocals and atmosphere, solid song writing, and audible bass tones.

Thank you in advance.

For Destruction, get The Antichrist. It's great modern thrash.

For Kreator, I like Extreme Aggression and Coma of Souls. Extreme Aggression is (obviously) the more aggressive and thrashier of the two, but Coma of Souls has some great melodic leads and riffs. Enemy of God isn't bad either. The early Kreator albums don't exactly have the most audible bass, however.

I agree with the previous Kreator recommendation, especially as regards Coma of Souls. For Destruction, meanwhile - if live albums work for you, try Live Without Sense. Otherwise, Cracked Brain as well as the aforementioned The Antichrist work well.
