How do you objectively compare the quality of one database model vs another?

I have two development agencies that have proposed two different database models. How do you objectively compare the quality of one database model vs another?

I suppose that if they both contain the same columns, even if they are in different tables, they'll be so close to each other that it isn't worth to really determine which is truly faster or, as you said, "Better" than the other.

The only thing I usually really look at is if everything column "could" be places in a more logical place, perhaps if something should even have it's own table, if the relations, foreign keys and primary keys are absolutely correct and shouldn't be different, and if the data that should be stored in them could truly be stored.

Perhaps I haven't done enough with databases yet, but that's how I look at databases.

Can I know what you mean by Database Model; can you be more detailed about it (what is it the agencies provided you with to compare)? It is difficult say anything without knowing the kind of artefacts they had provided.
 
Don't get me started about those stupid light bulbs.
