a mono is more like half an egg, a naturally strong shape.

There is a series of challenges and offsets in both designs. And they get addressed in specific ways so it is hard to impossible to tell what is 'stronger' or 'easier to build'.
You know, monos tend to have 20% to 50% of completely useless displacement
designed into their ballast. Then a cat does not need ballast (nor its attachment points) and so can be built lighter and sail faster. Then again, mono will 'give' so that any sudden loading on the rig will be dampened by the boat healing while a cat is a 'stiff' boat and so needs a much stronger (a mono sailor will shout here: 'overbuilt!') rig ...
So to say - each is different and has its own benefits, shortcomings and associates challenges in building and sailing them.
