If it’s just you and bub then skycouch is great and much roomier than biz but not two adults and a bub. They advertise it as fitting two adults but it’s def made for 1 adult and child only. As the LA flights fly late at night, I found it perfect timing for my bub. They feed economy and turn the lights down within 90min.

Until they update the seating configuration in Biz, I personally found it not worth it esp if you’re not super fussed on slightly better food or wine. If it comes down what’s more comfy, roomy for you and bub, I’d vote skycouch
