Well I am in sales and of course you are going to put YOUR product or whatever you have to sell in a position to seem to be the best. That is the whole point of sales isn't it.
With that being said, I still think AiB's are the way to go. In fact I believe any light inside the OEM angel eye is going to look dimmer at an off-angle. It is a function of the light ring itself. Even the headlights look brighter head-on than they do from a side angle.
