Great, do you use oil-based or water-based paint?
I am always using water-based paint
Is water-based paint more environmentally friendly than oil-based one?
Yes.  I like water-based paint only.  
Is Home Depot a good place to buy paints?
Yeah.  I agree that.  Correct one
Can you recommend some paint brands? Is Glidden Diamond good?
Yeah.  But,  I can't recommend any paints sorry.  Because,  That is your coices
That's fine. I would try Glidden Diamond next time.
That's good.  Your choice also good
