First, I love both companies and own multiple pairs of skis from both. Construction quality and durability of both are exceptional (I currently own 5 pairs of Praxis, and bought and sold one additional pair, of vintages ranging from 08/09 to present, and there is not a single sidewall gap to be found).
The BillyGoat, particularly RES is a more revolutionary design. The GPO definitely has a similar design in the tip, but not quite as well developed as the BG. It works 90% as well in soft snow, I would say.
I bought the BillyGoat for resort skiing because I like the damper feel of ON3P's layups for choppy resort snow. I bought the GPO for touring because a carbon, medium/stiff 187 GPO is 0.5lb lighter than a 186 BG Tour AND because I could buy a carbon GPO for $490 during the presale, whereas the BG Tour is $899. The weight difference is noticeable, the price difference was huge.
