I started with a jacket and now dive with a bp/w, and I feel like it's easy for me to roll around and position myself however I want to be in the water to see what I need to see. I can't say for sure whether it's easier than it was in a jacket, because I haven't tried a jacket lately and I'm a better diver now than I was then. But I do remember the first time I used a bp/w--even though it was a rental and I couldn't adjust the crotch strap tight enough for a proper fit--I was struck by the awesome sense of control on that first dive. I noticed a further improvement the first time I used my own, with the straps all adjusted just right for me. If you have the option to rent one, try it out!
