I played with both so here is my 2 cents:
Power: Aerogel 200 has more especially on the serve. In fact this is the best serving racquet I ever used, effortless power, you don't even have to try very hard. For the KBlade Tour you have to bring your own power.
Comfort: The Aerogel is very soft and buttery, very comfy, very nice feel. The KBlade Tour is stiffer but not really stiff, more like medium range, shouldn't give arm problems to most people. The feel is very muted.
Stability: The Aerogel is very solid and stable, large sweetspot, feels like a rock, reminds me of the nCode 95. In fact I would say that the Aerogel 200, along with the nCode 95 and 90, is the most solid and stable racquet I ever played with. The KBlade Tour doesn't have enough mass in the head to be as stable as the Aerogel 200 or the nCode 95 but it's still a fairly stable racquet and some lead tape would probably improve things. For me the Aerogel 200 doesn't need any lead tape or customization of any kind, it plays great bone stock.
Control: Aerogel 200 has very good control, it's one of those rare racquets that have plenty of power on the serve but it's still low power on the groundstrokes. The KBlade Tour is practically a control freak, almost imposible to hit long if you don't open your racquet face, good spin despite the tight string pattern. If it's control you're looking for, then the KBlade Tour should be at the top of your list. The drawback is that it's hard to generate power on the first serve.
As you might have guessed, I really liked the Aerogel 200, and if Dunlop cuts the price to bellow $100, like they did with their old series, I'll pull the trigger.
