Can’t decide which program to start

So, over the years I’ve purchased many programs. I never finished any of them till the end :/ but that's on me. I always gave up. I have this really subborn fat on my belly. Now my question is, since I have finally summer holidays, i can finally focus on me, on healthy eating and working out.

I don't know which program I should use though. Because I mostly wanrt to get rid of my belly fat I'm deciding between fbabs and fbfit. Which one would you recommend based on your experience?
