I use both in our woodworking manufacturing environment. For general finishing usage either type of sander works well. The random orbital is more applicable for production work. Using finishing grit grades (140-160-180 grit there should not be any visible scuff marks on most any hardwoods using either type of sander. Note that many woods give off the sanding dust that is flammable and that can damage lungs. For this reason I lean towards the Bosch or Porter Cable models that have the dust collector assembly which will generally keep the dust from being a breathing irritant.

Good luck on your project
