Top Law Schools

I've read a few comments on this forum and elsewhere that the Manhattan Logic Games Study guide had a better approach to Grouping games than the Powerscore Logic Games Bible.

I have powerscore and have been debating whether or not I should pick up the Manhattan book for grouping game help.

Could someone elaborate on the differences between the two approaches?

Thanks in advance.
