Tukey's Test is just one of many methods available in post-hoc analysis and as mentioned, is considered to be the best method in a wide variety of cases.

Post hoc analysis is an important procedure without which multivariate hypothesis testing would greatly suffer, rendering the chances of discovering false positives unacceptably high. Ultimately, post hoc testing creates better informed scientists who can therefore formulate better, more efficient a priori hypotheses and research designs. As the number of comparisons increases, the post hoc analysis must lower the individual significance level even further. For our six comparisons, Tukey’s method uses an individual significance level of approximately 0.011 to produce the family-wise error rate of 0.05.
