What spelling is better for our boy

Go with Kamari.
As the Marie in Kamarie is more feminine.

Agreed with first comment .
As a lady with her middle name Marie 😂 , it’s too feminine.
Kamari seems more masculine for a boy 🩵 congratulations 🎉

I feel like those would be pronounced differently because the emphasis would be on a different part of the word. For instance, I would pronounce Kamari as ‘Ka-Maar-ee’ with the emphasis being on the ‘mar’ whereas I would pronounce ‘Kamarie’ like ‘kama-ree’ with the emphasis on the ‘Ka’ if that makes sense. So for the pronunciation you want, I’d go for Kamari 😊
