As a Class-DBI Con you have
Single author => single point of failure
but then, in the DBIx-Class Cons you have
Multiple contributions => less coherence expected.
What do you think is better now, more or less contributors?
Also, DBIx-Class seems to be both, the "Second worst performance" and the "Second best performance" which both are Pros and Cons in your list. Is it really both a pro and a con when it is in the middle?
No support for customizable column inflation/deflation. (is this true?)

Also, what do you mean by No support for static class metadata generation.? If you mean DBIC can't create the classes for you, you haven't taken a look at DBIx-Class-Schema-Loader.
Also, your DBIx-Class Con list contains both of these:
Does NOt have seamless support for handy database domains (production, test, dev, staging, ...) and types (main, archive, reporting, ...).
