If you're a fast painter who makes messes, Acrylics the way to go
If you don't like fumes, acrylics the way to go
If you are tired of waiting for oil to dry, Acrylics the way to go.
I can go on and on about why acrylics are the way to go. But Someday I will also add oils on top of the acrylics but not now :)
