Some ways Bayesian data analysis can be useful

1. You can include information sources in addition to the data.
2. You can make any comparisons between groups or data sets.
3. You can use the result of a Bayesian analysis to do Decision Analysis.
4. You can change the underlying statistical model.
5. Bayesian inference is optimal, kind of.
