Have you bought a compendium? And did you like it?

I just started reading comics a few months ago, so I'm fairly new to this.

I enjoyed the Injustice video games, and I've heard the comics were great, so I figure I should read them. The comic book store near me has the individual volumes for Year 1, Year 2, and Year 3. But they also have the Injustice Compendium, which has everything in one book. And the compendium is absolutely gigantic: literally like a phonebook. It just seems like it would be unpleasant to read, impossible to carry around, and most of the pages would have a severe curve when they're open from the inflexible spine.

Have you bought one of these before? Did you prefer it over having individual volumes?
