New to Scala;
The major performance issue with Skunk is tracked here. tl;dr prepared statements currently take a horrifying number of network round-trips to the database. I'm sympathetic to Rob's "what you see is what you get" priorities for Skunk. But I'm glad to see an outline of a plan that sounds like it would satisfy those objectives without being so, for lack of a better term, naïve in their pursuit.

Pleasant to use Scala libraries
The same creator is working on skunk, which is very exciting. Only works for Postgres though.

Zio / Zionomicon : is it worth it ?
The libraries doobie and skunk are more closely associated with cats. They both use cats-effect and fs2 for implementing database connectiona and input-output operations. The doobie library is a wrapper on JDBC, and as such is compatible with many DBMS, such as MySQL, PostgreSQL, H2, Oracle... Whereas skunk is specific to PostgreSQL, and is based on using the server protocol of that database.
What are some alternatives?
