I used to use only oils, but after putting much, much effort into it, learned to work with acrylics.
At the time, I was teaching many Tole & Decorative Painting classes and students were wanting to use acrylics for the convenience. One of the things I learned was in using craft type of acrylics for most things because there doesn't have to be as much color mixing. They are cheap to buy & actually have a little working time. Or maybe I have just learned to work fast!
If you really want to use tube acrylics and still have some open time, try using a retarder which will slow the drying time somewhat. Working in glazes, layer over layer as is often used in watercolors is another way to achieve a beautiful look.
But I am with you about using oils. Though I seldom use them these days, they will always be my first love!
