I think it's a very personal choice because losing the weight depends on a number of factors. From my personal experience, I gain weight on WW's, anything low fat, high carbs, following the food guide plumps me up for Thanksgiving. So...low carb is really the only way I lose weight at all, I've been gorging on carbs so long (nearly a decade and a half, and I'm only 24) my insulin reisistance is something terrible. On weight watchers after a month I was up 5 pounds (doing it religously) and on Atkins I'm down 18 pounds in 4 weeks.
I too love carbs in every form minus sweets, I prefer the salty stuff so even the amount that WW allows is a death sentence, they allow an inch and I want a mile. On Atkins honestly you stop wanting that stuff completely, except for the emotional eating times when you need a comfort food. It is very liberating.
After all, I'm a wee bit biased about plans too cuz this one is working for me and nothing else ever has. But Goodforme is right, it's easier (and works better) to pick one and stick with it.
Good luck making your choice, and which ever way you go there's plenty of support to be found here
