I own Faction Prodigy's and ON3P Jeffreys.
I have to say I LOVE both of these skis. Durability is very comparable with ON3P getting a slight edge. The Factions are a pretty soft ski, and the Prodigy is an awesome all mountain ski. I mounted marker barons on it and I use em for touring now as they are a lot lighter than my Jeffrey's (they're 174 and the Jeffreys are 181, so that may account for most of the weight difference). The reason I consider those mainly as my touring ski (also early/late season hardpack/rock skis), is because the Jeffrey does everything else. I have taken the Jeffrey's out in pow, on hard groomers, in moguls, whatever you want to do, the Jeffrey's will dominate. They are stiffer and heavier which means these bad boys BOMB everything while the Factions are more fun for carving and dicking around.
I highly recommend both skis/companies. They have served me well in Summit County. The only other skis I've had since I moved out here are Surface One Lifes, and they did not seem as durable and I just didn't really like that ski.
