Herr_Noobien, I have 2 BM 530s (one in 440C and one in 154CM), and I absolutely love them! They're one of the few Benchmade models out there that I like (the 800, 970, 710, and 730 series being the only others). They are pretty much folding 'boot knives,' so if that style appeals to you, you'll like 'em. They are extremely lightweight and thin. The handles aren't what I'd consider the strongest, and the grip isn't very ergonomic, but they work just fine for daily tasks. They have very thin blades, which make them great slicers, and the spear-point shape works very well for almost any task.
One of the reasons I got both of them was to compare Benchmade's 440C to their 154CM, and since everything else about them is identical, I figured it'd be a great way to do so. To be honest, I haven't noticed any difference whatsoever between the performance of the blade steels on the knives. Both knives sharpen up very easily and both take a very sharp edge. I also really like having the Axis lock available in such a lightweight knife. I'd have to say that the BM 530 is a 'sleeper' in the knife world. It is most likely the strongest folder available in its weight class!
