I would get a male clown since you can throw him at any other female morphs you have, but there is something to be said for raising up a female clown as well. A visual female proves invaluable down the line.

I picked up a male clown and a female lesser 50% het clown/hypo. If she proves out, great. If she doesn't, hopefully she'll give me a male lesser het clown to throw at one of my het females.
