'unzureichend' means that something is not enough or does not meet the requirements. 'genug' is neutral and very common in everyday language. 'unzureichend' sounds somewhat more factual and is often used for evaluations, results, or performance. The simple contrast is: 'genug' is enough; 'unzureichend' is not enough.
