Monitors... video only or video and owlet!!!

So my husband and I received a video monitor for little one that is due in February. He thinks that the video monitor is sufficient however I believe that I want the Owlet as well. I believe that being able to see the baby plus measure oxygen and heart rate levels will give me more peace of mind than the video monitor alone… What do you ladies think? Do you think The video monitor is sufficient alone? Or would having the Owlet in addition allow you to have a bit more piece of mind???
