I will be ordereing one of these two strobes this Friday. In many different forums there seems to be a difference in opinions on power. Some say theB400 @160w/s is better because Digital Camera's don't require much power . Other say always get the most power. I am now very confused about this issue. It seems to me to be more about the speed of your lens than anything. When shooting portraits I generally want to blur the backdrop and will open the aperture as wide as possible. This would mean being able to reduce the light down as to not get hot spots. I could see only using a high aperture if I am shooting a group. Am I missing something here?

Get as much power as you can afford... two benefits:
1. You can shape thoses lights through reflectors, panel/diffusers, umbrella, or color filters etc... all theses techniques (also to reduce hotspots) will cut down the light output by spreading out over larger areas.
2. Closing down the aperture will also allows for a sharper picture. This will allow you to darken/blacken out the background differently than defocusing it: http://www.lightingmagic.com/bkgndqa.htm
3. You can always reduce the power, but what happened on occasions when you need more it, when you're already maxed out? Some folks happened to use them outdoor too...
