Comparing percentages is the best choice because it allows for a clearer comparison of groups of each size. Percentages standardize the data and allow for a more meaningful comparison between groups with different sample sizes. Comparing frequencies alone can be misleading, as larger sample sizes will inevitably have higher frequencies, even if the proportion of individuals in each group is similar.
