Final or Recital?

I am taking organ lessons at the college this semester. At the beginning of the class, Dr. Carlson, my instructor, informed me that at the end of the school year I would have to give a final in front of a couple of the keyboard faculty. But today, she told me that if I would perform on a mixed student recital, I would be exempt from having to give a final. In other words, I could:

Play five or more scales and two pieces before a two keyboard instructors for a grade or,

Play one piece in front of the instructors and attending music students at a recital for a grade.

The latter option sounds very appealing to me. I have been learning Prelude in a minor by Benedetto Marcello. Played with a full organ sound, it begins with a fast, cascading waterfall of 16th and 32nd notes. The introduction leads into a short hymn that contains some very strong dissonances, e.g. a chord containing c-sharp, e-sharp, g-sharp, b, and d. It is a very impressive piece. I cannot wait to perform it on the school's recital organ.
