Green Screen vs A miniature set

I've been getting used to green sceen, but It doesn't leave me satisfied. Sure, it looks cool and semi-realistic but eh, its ok. My miniatures take up a lot of room I don't have and they look cool, I can get shots with their feet on the ground and I can zoom out more.
I dont know really.

Yeah. I like these, plus I can put masers.

Thats my greenscreen
