asmatt, you are not going to get any of those planes to fly as well as the katana or any other 60 size profile for that matter. This is because these 60-70 size profiles have over 1000 inches of wing area but weigh in at 6-7 pounds. My katana came in at 6.4 pounds with my sk 91 2 stroke. Hovers at 35% throttle. No matter were i point the plane it just doesn't want to stall . All of the planes you have listed have 800-1000 inches of wing area but weigh in at 9-10 pounds. To fly really good 3d you want the plane to be lite on the wing but still have a good power:weight ratio. Unless you get a profile you will have to compromise between the two. You will either have a plane that is underpowered but very lite on the wing OR you will have a overpowered plane that flies like a brick. The katana 70 profile or mojo 60 for that matter will give you a very good power to weight but will be VERY lite on the wing.
