Following a disastrous event known as "The Second Impact," humanity teeters on the brink of extinction. Having not completely eradicated mankind previously, creatures known as Angels begin attacking once more in an attempt to create a third, and final, catastrophe which will annihilate mankind once and for all. When conventional weapons fail to stop the Angels, however, the Japanese military organization NERV proposes the use of strange mecha called Evangelions. When the first Evangelion rejects its pilot, though, NERV's commander is forced to draft his estranged son, Shinji, as mankind's savior. Bitter of his father's estrangement and insecure in his abilities, Shinji struggles to overcome his doubts and fears in the face of certain death, but ultimately continues to fall short despite his efforts. As he slowly improves his skills, however, he must come to terms with the greatest question of all: is humanity worth saving after all?
As the mighty star fleet of the planet Keron prepare their invasion of Earth, Sergeant Keroro and his elite team of commandos have been sent to infiltrate the enemy strongholds and gather as much intelligence as possible. However, it seems even his extensive military training is no match for the forces of Earth, as he is discovered and captured by the two middle school siblings, Fuyuki and Natsumi. Submitted to the rigorous torture of housework duty, the amphibious Keroro must now bide his time, covertly locate his squad-mates, and resume his mission of conquest!
If you liked SGT Frog or Evangelion you'll like the other because most of the human characters in SGT Frog are parodys of Evangelion characters. Fuyuki is a parody of Shinji and Natsumi is a parody of Asuka and Aki is a parody of Misato and so on. There's also an episode where they Evangelion itself as well as the characters. By the way it should be noted that SGT Frog is intended to be watched by children and Evangelion wasn't though that shouldn't hinder you from enjoying ether show.

However, upon breaking out onto the surface world, Simon, Kamina, and Yoko encounter enemies more powerful than they could have envisioned. Their fight for adventure just turned into a war for the survival of the human race - will their lust for freedom hold out against such terrible odds?
Though quite different shows, I feel both will appeal to the same viewers due to mech of epic proportion, dystopian backdrop, and crisp art styles. Both utilize computer graphic editing in such a way that it isn't overtly obvious as in many anime of similar genre.
