Regular MH or Super MH (blue enhanced)?

I'm trying to pick an MH bulb for vegging. So should I pick regular MH or Super MH (blue enhanced)? What is the value of the added blue spectrum for MH vegging?

I'm a new grower, so correct me if I'm wrong, but I thought the main purpose of the enhanced blue spectrum was to enable HPS bulbs to be used for both vegging and flowering. If that's true, then what value does the enhanced blue spectrum add to MH vegging?

Thanks

I don't think any one knows. I have been searching for same answer and can't find it. I'd like to know as well
As I don't want to spend 100 bucks on a mh bulb if its not going to do much more.
