I agree. It's not as good. I can see that the long bristles on the duster you're using get right in to the crevices which is where the bits get stuck.
But for my own personal needs it's better. I need something that I can very occasionally just whip out at a moment's notice to deal with a particular cobweb or mucky door frame and then pop back in my BOAB and then get back to work.
And I don't use it on high areas. If the little cobwebs are on upper floor windows, they just get left, I'm afraid. There are limits to what's achievable.
