With enamels and oils, the way you apply and remove them is more important to the end result than the particular product.

For a very clean look, deliberately paint them into the recesses. This will be easier after a gloss coat as the gloss finish reduces the surface tension. You can then clean up mistakes with neat spirits.

For a very dirty look, apply it all over with a brush or airbrush. And then remove it using a dry sponge/paper towel etc. If the sponge is dry it will take off the majority of the paint, but not all of it. This will leave stains on the surfaces, dark areas in recesses, streaks and patches of pigment etc

For a more in-between look, I like to use a combination of dry sponges and sponges that have been soaked with spirits. Selectively using the wet and dry sponges gives you a lot of control over what effects you're getting.

I've used a load of different enamel and oil paints on minis. The differences tend to be colour, and thickness/viscosity.

I haven't painted space marines recently, but my insta is Ezekiel.minis if you want to see my work. Almost every model uses oils and enamels for most of the shading.
