You should use the Experimenter for generating such comparisons. It
will tell you whether the differences are statistically significant or
not. You can then also evaluate other measures, like root mean squared
error (RMSE), F1, precision, recall, to check whether the differences
are still significant.

Check the manual PDF that comes with Weka on how to use the Experimenter.
