I see this question asked often. The most recent was a GMT m2m thread. The person asked if it was a NOOB or a BP. That got me thinking, why ask if its one or the other. I know they have subtle differences. But I think if you can't tell by looking at it, does it really matter which one you buy. If you have a preference you should know the difference and not need to ask. Which brings me back to why ask. I'm not making a judgement on people. Just genuinely curious why people would ask this. Cause me personally if I had a preference I would know what I was looking for and wouldn't need to ask.
