The BK2 is worth the extra money, for the most part. Not because I prefer it. I don't own one, the grip design just doesn't do much for me.
Here's why I say that:
You're buying a product proudly made in America, by a company that puts it's customers first, and stands behind them 100%. Overall fit and finish is better, and the 1095CV is a bit better grade of steel than the 1075 the Condor offers. It is a 1/4" thick blade, with a high saber grind. You'll be hard pressed to find a stronger design for less than $100. You can also upgrade or customize your handles on the Becker, which is important to some people. If you like plastic sheaths, the one with the BK2 is a good one.
Condor is also a very good company to buy from. They have great feedback regarding their customer service and they might just be one of the best values, dollar for dollar, on the market. The Rodan is a flat grind, 3/16" thick, with a convex edge. It SHOULD be a better slicer than the Becker, but I can't say that for a fact. The handle on the Rodan is as indestructible as a handle can get. Condor's tend to come with very nice leather sheaths too. The 1075 steel that they use is tough and holds a good enough edge. Folks that have the Rodan and have actually USED the Rodan have nothing but great things to say. If you shop around, you can almost get 2 Rodan's for the price of the Becker.
I think that either one will make you happy. In the end, it depends on where you want to send your money and how much you want to spend, I guess. What one will do, the other will do too.
I'm planning on buy some Condor stuff in the not so distant future to experiment with myself.
