comparing SPARQL queries against Jena TDB to SQL queries on MySQL or Postgres is like comparing apples and kangaroos.
In the sense that apples rot and Kangraroos are amazing animals which can do just about anything?
Because otherwise the comparison seems completely apt.
Jena works for RDF data. But the OP is correct in their broader point that RDF is rarely a good choice and SPARQL is a pretty horrible solution for querying it.
Note that the reply someone is about to write ("But RDF is a generalized self descriptive data model") means it is intended to solve the exact problem that a RDBMS+SQL solves. And if you add the "standardized fields" thing it also matches the REST interface+RDBMS+SQL comparison the OP made.
