What are the pros? Healthy plant
What are the cons? Bitter fruit!
I got a dud -- the fruit is horribly bitter! I'll try again next year and hope to get a better plant. Note that bitter zucchinis are seriously toxic, so if you ever come across one, don't soldier through and eat it anyhow! I know people who ended up in the hospital from doing that.
The tendency to bitterness is genetic, but not straightforward. Here's a useful reference about the occasional incidence of bitterness in summer squash. http://cuke.hort.ncsu.edu/cgc/cgc06/cgc6-38.html
