No way. The formulation has definitely changed for the worse. Perhaps it
only works effectively on Monsanto's genetically-engineered weeds. 
The branded stuff aka Roundup, Weedol just has less of the active
ingredient (glyphostae) that the generics, they may have some
surficants to aid penetration though.
I wonder if a little squirt of dish detergent migh be helpful?
I'd just get the highest concentration I could, dilute if required
and bruise the target plant a bit. It does take a while to act, some
plants are quicker than others and some tough buggers can take more
than one application. Just be patient, it does not produce an instant
knockdown. Indeed by the way it works you don't want an instant
knockdown.
It's not so easy to decide which brand has the highest concentration.
Seems to have been made a little obscure, perhaps on purpose.
