Series are quiet different, for one they are based in different eras and Berserk is more bloody.
However, if you look over this you can find a similarity. Both shows are about war and a specific group of people that is getting engaged in battles. Both series have wave war action and strategic planning, constantly tryong to come up with effective tactic.
If you like shows about war where strategies and planning are constatnly made, bothe shows will work perfectly.
