Why is lead iodide a better choice for investigations of balanced chemical equations?

By not having well-formed crystals, impurities can easily crystallize into the solid. By having well-formed crystals, it is more likely that your substance is pure.
(This doesn't always hold true, because many elements are intermixable - like Carbon and Iron to make steel.)

Lead iodide would not be a better choice for "investigations" of balanced chemical equations. Even in the lab, both chemicals have limited solubility in water, which is kind of essential for writing chemical equations (at a beginning or elementary level). Magnesium hydroxide has a solubility of only one part in 80,000 parts of water according to the Merck Index while lead iodide has a solubility of one part in 1350 parts of water. Don't got nothin to do with "nice uniform crystals".
