I've done both. I did Momentum a few years ago and did it for about a month on my own before switching to Point+ (and officially signing up for WW) at the end of January.
Personally, I LOVE PP. I feel it's more flexible and I'm left feeling more full and satisfied at the end of the day, whereas on Momentum I often felt hungry or I felt like I was on a diet. With PP it's more like it really is a lifestyle eating change. In the past six months on PP I've lost 33.6 lbs. I lost more weight in a short period of time on Momentum, but there's no way I would have been able to keep it off long term (and I couldn't even keep it off six months, as I gained it back and that's why I'm on WW again!)
But I do know there are people who have not been as successful and their body prefers Momentum and there are threads here dedicated to that plan. I think you just need to find what works best for you
