IMHO, I don't think your question is specific enough. I'd make it either a play OR a musical. In the case of musicals - I don't have a preference as long as the story is good. PARADE is a tragedy - and yet it's one of my favorite shows. THE PRODUCERS is a comedy - and yet it's one of my favorite shows.
For plays, I prefer to see professional tragedy productions and community/school comedic productions.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
