Which is the better saga to read, Attack on Titan or Jonathan Hickman's "X-Men" run?

By Jonathan Hickman's "X-Men" run, I'm referring to everything he wrote from House of X and Powers of X up till Inferno.

So, I've been noticing a new trend that's been ongoing throughout the site that likes to compare several comic book and manga titles with each other albeit some of these comparisons have been rather ... odd at the very least. However, I'd like to compare two of the most celebrated manga and comic book sagas from the last decade that I find to have somewhat similar themes.

Both of these sagas are about people and their nation who suffered from discrimination to the point of death from enemies throughout the world as well as within the nation itself and the powerful message of never giving up hope throughout multiple generations and lifetimes in order to give your people a good future in the long run (even if you need to rely on underhanded methods sometimes).

However, what do you think is the better saga to read?
