I have a Sage I, and find it every bit as good as the reviews. Compared with your Persistence (I do not own one, just going by specs), you get better steel, larger blade, same weight, and imo even better ergonomics and handle material. I really like the "choke up" choil on the blade. The CF handle material has just the right grip and a very good feel and continues to look great after pocket time. It also looks a little dressier than G10, so while it is a hard worker, you see it recommended as a gentleman's knife as well. I have never used it with gloves on or in wet conditions, so I can't say how it compares to G10 under those conditions.
The workmanship is first rate, the action is smooth, and the lock-up is very solid. I am relatively new to quality knives and this was my first $100 knife, so I gulped a few times before ordering it. I was not at all disappointed. In fact, the design and execution are done so well that it seems like good value if you want to be in that price range.
