Snoogle vs. Boppy Body Pillows?

bustle

Any experience with either?  I have read reviews on both and they both seem to get mixed reviews, either people love them or don't.  I also thought about going the cheaper route and just getting a body pillow, but don't know if that will work as well. 

I know side sleeping is recommended and have been trying to transition the past few days.  However, I keep waking up and am on my back.  Figured a pillow would prevent me from rolling over in my sleep.  As I progress further though, will I also need something under my belly or between my legs? 

TIA!
