As others have pointed out, you can't compare the two systems. They are totally different in terms of how points are counted, how many points we get, and how many points food is.
Points Plus works for some people, some people choose to stay on the old program, although it is not currently officially supported by Weight Watchers. I would suggest at least giving PP a chance, and that means eating all 28 of your points, before deciding whether you want to switch back.
Plus, all of us have "not so successful weeks" every once in awhile despite staying on plan. It's just part of the journey
