Over a century ago, mankind was devoured by giant beings of unknown intelligence and origin known as Titans – creatures that eat humans alive indiscriminately and for no apparent reason.

Eren and Mikasa have lived a relatively peaceful life behind the city's walls, but when a massive Titan appears, smashing the outer barrier and unleashing a wave of terror, their lives are brutally changed forever...

Both stories involve a defense force that fights against giant monsters and a protagonist that is motivated to fight those monsters, ends up becoming a monster, and takes advantage of feir new monster powers in fighting the monsters.
The plot is kind of similar. It revolves around humanity survival and fighting big creatures. The main protagonist, although is much older, also becomes one of the creatures they're fighting against to.

When Edward and Alphonse Elric try to revive their dead mother, breaking the taboo of human transmutation in process, Ed loses his right arm and left leg while Al loses his entire body. After the tragedy, an alchemist named Roy Mustang visits them and tells Edward to become a state alchemist to find a way to recover what they have lost. Accompanied by Al, whose soul is now attached to a metal suit of armor, Ed is fitted with auto-mail parts in place of his lost limbs and becomes a state alchemist by the name of "Full Metal Alchemist." Together, they set forth on a journey to find the Philosopher's Stone - the one item that is rumored to have the power to restore them.

This is a gut feeling thing, but I'd say if you like the tone of one, you'll enjoy the other. Both deal with monstrous things and some serious implications, but manage to smoothly break up the mood with comedy. The style of humor is similar, I feel.

I don't really know why but when i started reading Kaiju No.8 the first thing i thought was that it really resembles Fire Force. In both manga the mc wants to join the special forces to help out and make their chaotic world more peacefull.
