The larger the value, the larger the distribution differs from a normal distribution. The problem is that if you want to examine the effect of a highly skew distribution, you must also have a distribution with high kurtosis. An extremely closely related question concerning the two-sample t-test - effectively a one-way ANOVA with two levels in the factor - is, I agree with @rolando2: "skewness is worse than kurtosis" or vice versa is a rather vacuous statement without mentioning the degree of skewness/kurtosis.
