Painting on wood panel is different from painting on Canvas. Panel is smoother, devoid of texture and firm under the brush. And I’ve experienced that colors dry faster on Panel, even with the priming underneath.
Oil Paintings on Canvas have their own advantages though. For larger paintings, Canvas would be a wiser choice as it is lighter. MDF or other wood panels run the risk of warping or bending under their own weight if the size is too large.
