Model flexibility allows conceptual transition from generic descriptive models to domain-specific models wherein parameters serve psychometric purposes.

Bayesian methods permit different sample sizes in different groups, and different sample sizes per subject, unlike traditional ANOVA which has troubles with unbalanced designs.

Bayesian methods allow data collection to stop at any time, unlike p-value based decisions that require a pre-set stopping criterion, such as fixed sample size, and no peeking at the data.

Bayesian hypothesis testing permits a principled way to assess evidence in favor of a null hypothesis, unlike NHST. Bayesian methods allow cumulative science and use of prior knowledge for leveraged inference when data are sparse, unlike traditional methods.

Power and replication probability are straight forward to estimate with Bayesian methods, but difficult to assess in p-value based methods. The tutorial does not address all the points listed above, but does illustrate many of them with examples from linear regression and ANOVA. For a brief discussion of several benefits of Bayesian data analysis, along with a worked example, and an emphasis that Bayesian data analysis is not Bayesian modeling of mind, see Kruschke c.
