Durability, lifespan, price, stability, installation, and appearance are the key factors when comparing prefinished wood floorings. Prefinished engineered and solid hardwoods have high durability, and a long lifespan. The final finish on the wood gives protection to the surface, and therefore a good quality engineered wood with a thick layer will do the job.
There is not much difference in prices as may seem expensive for a red oak solid in comparison to an engineered oak. However this might not be the same when comparing different grades of solid wood or engineered wood. Best advice is to go with the budget and pick the best.
Installing either of the flooring is not much effort apart from the fact that unfinished solid wood may take a while to acclimatise at the home and also need multiple layers of finish onsite. We also recommend you consult with some engineered wood flooring specialists before making a big purchase for your house.
Prefinished engineered wood is better resistant to moisture and humidity in comparison to Solid wood as it is constructed to resist changes with temperatures. For the looks, it is better to check a pre finished and fit finished hardwood. All prefinished will have bevelled edges. In terms of aesthetics they both are same since the top wear layer of engineered wood is same as solid wood plank.
