Thank you for your question, Juanito.
Ben Wright's summary of raw-scores vs. linear measures at
http://www.rasch.org/rmt/rmt61n.htm may help.
For the test constructor, an obvious advantage of Rasch is the ease with
which Rasch methods accommodate missing data.
For the consumer of test results, an obvious advantage is that Rasch
produces pictures (maps) of performances and of the latent variables.
