I totally agree with their personal pref. I find OG too easy as well, esp I thnk verbal insufficient! However, the Xplanation is vital and u need it to 了解gmat的思維.
Kaplan I bought in transit from London/HK, its good but there are some lvl diff, OG difficulties goes from RC/CR & SC, but Kaplan is diametrically opposite, its RC can be interesting, but CR & SC too simplified.
Princeton, well I had a look at it in HK airport during an work conference and like the Others (3 above...) wasnt too impressed.
Personally if you memo OG, then you shld be getting 27+, and GWD 34~ with PP & JJs 40 easy. These are the foundations I would start with.
BTW I highly recommend you getting hold of A. rabbit's monthly JJs, either borow or buy it as it is highly organised with most dissension & conflicts iron out. If you cant find on CAFE pm him stead.
My verbal exam result from doing Kaplan only was 37, so if I had A.rabbit's JJs & PP.......
