Tung (Danish) oil is not much different to work with than linseed (now that is messy). Tung dries faster and much harder than linseed. If you used "pretty" wood and it were me I'd go the oil route. . Scratches don't show much and a little steel wool, hit with some oil and everything blends right in.

With an oil finish people say how nice the wood looks, with poly they say how nice the finish looks.. Good stuff..<°)))>{
