Since the change to pp they're a lot more similar tbh. On WW all fruit is free, even pineapple!! But the veg aren't, potato, parsnip, sweetcorn, peas all carry points. You get a minimum of 29pp daily and then get 49 weekly points (equal to your syns) to use throughout the week. But there is no carry over of daily points, you don't use them you lose them.
I kind of find it a bit like sw with portion control - the reason i switched over!
