What insights can we derive from the mean of squared residuals and % variance explained terms in a randomForest model?

hello,

What does the “mean of squared residuals” and the “% variance explained” in a randomforest model explain about the model? How do we compare two randomForest models -
(1) one with low mean of residuals and other with more.
(2) one with low %variance explained and the other with higher.

thanks.
