It's as fair to judge Pathfinder based on what we have seen so far as it is/was to judge 4e based on previews.
Maybe, if you are judging things about the Beta of Pathfinder that definitely are not going to change against previews of 4E that occured once the books had gone to the printers, or you are judging things about Pathfinder that will change against previews of 4E that did change before the final galleys went to the printers. Probably better to compare Pathfinder aspects versus situations in 3.5 play that were problematic and try to get Paizo to recognize such things and change them prior to finalizing their changes. That has more potential of being a worthwhile pursuit at this point in time.
