I have been using acrylics more lately. The solvents and the difficulty of dealing with disposal and slow drying time of oils makes acrylics an easy choice if it were not for the advantages of painting in oil. Someone compared the difference as painting with margarine or butter. The texture and body of oils are wonderful. Acrylic just flattens out when dry.
I have been using Windsor and Newton to start with block in and then moving to Golden Open for slower drying time. The quick drying of the W/N paints is nice to set the stage. I find that they dry Too quick outside though. In this case the Golden paint is great from start to finish.

This small painting was done on the spot in Manitou Colorado to the west of Colorado Springs CO.
Done entirely with Golden Open acrylic. Painted on linen taped to hardboard. I like the surface of Centurion Linen in their primed pad.
