I love sw too although for me the meetings keep me focussed so I would only do online if I knew I was able to motivate myself. The my fitness pal app is great for calorie counting. I think its important to be realistic about how you like to eat and the types of food. Sw is great because you can have larger portions if hungry, on ww or counting cals once your numbers have run out that's it and I find that difficult. Think what's best for you and go for it!
