Tukey's HSD test is the best post hoc comparison to use when the sample sizes in all levels are equal. This test is specifically designed to control the overall Type I error rate while making pairwise comparisons between groups. Fisher's protected t-test and the orthogonal t-test are also commonly used post hoc tests, but they are less powerful than Tukey's HSD test when the sample sizes are equal. The equal ns t-test is not a post hoc test, but rather a test of differences between two independent means with equal sample sizes.
