It's not being nitpicky. Chuunibyou simply doesn't have anywhere close to as much thematic depth as Hyouka. You can think it's good for other reasons, but it's not a show that says anything meaningful.
Depends on what is meaningful to a person.
Its relative to personal experiences and what an individual feels is relevant to their life or not.
This is one thing about criticism of a show as objectively good or bad.
People look for different things when they watch something.
Sometimes they just want something funny or cute. Sometimes they want depth and story.
Sometimes they want abstract ideas or themes.
No two people watch anime and extract the same experience. Thats why anime is so enjoyable.
We all have different views about it.
Suppressing anyones viewpoint because its too lowbrow or highbrow is kind of missing the point of this community.
