I have both. The PM2 has better ergos and just feels better in the hand. But $185 is a bit high when if available at a reputable online dealer they usually go for around $125. The wave feature on the endura is fun, and I prefer the blade shape of the waved endura over the regular one. The PM2 compression lock is the best lock IMHO that spyderco makes. For $90 the waved endura is a good deal. So. U pays ur money, and either way get a good knife. The wave feature looks like ur pulling a long fixed blade straight out of your pocket.
