Moreilavirdis or Corallus caninus ?

So I've been looking at both green tree pythons and emerald tree boas as an arboreal snake. If anyone has kept both or either one tell me how they like it. I'm planning on buying one within the next year and I know the general care for both 85 hotspot, 60-80% humidity, perches, some fake plants or live, heat panel, thermostat, water dish, newspaper or cypress mulch. But is there any little details some of you guys have noticed in their care? I'm leaning more towards emeralds and are aware of their huge teeth as adults. But I also love aru and sorong green tree pythons. Anyways can someone with experience of them tell me which you like more and why. Thanks
