I've heard the low fat is better than the low carb, but it depends on your personal tastes and what you think you can live with. I went with the vegetarian plan, which was also low fat. I avoided the soy products after the first taste, lol. But there were some very good meals in there. My only real complaint was that they didn't include instructions on how long to reheat the foods, or if the microwave was the best method for certain foods, etc. I had to wing it, but everything turned out ok. I made sure they were thawed before heating.
I also tried the 3 Hour Diet and was very impressed with the quality of their foods. They didn't offer much for vegetarians, so I strayed and ate some seafood
I even had lobster one night!
If diet meal delivery turns out to be the way you want to go long term, I'd suggest trying them all so you can compare them and see which you like the best. There's a big difference between them all. Most are really good, but there may be some aspects to some that you don't care for. I really enjoy the convenience of having someone else do it for me. I'm not using a diet meal delivery service at the moment, but am living on frozen dinners. Not Lean Cuisine style, but some all natural brands such as Seeds of Change.
NutriSystem or Diet to Go?
