a laminate floor will scratch less than a hardwood floor (however a hardwood floor can be refinished,not a laminate)...most brands of laminate will work fine,i dont think any one is much better than the others...(stay away from the $.99 stuff) home depot has a 25yr warrenty product for $1.99..called hampton.................good luck

Had a friend install engineeed hard wood floors and in less than a year his dogs had ruined them and he had to sand and re-finish (which can only be done once with engineered wood floors). Laminate is much more resistant.

Engineered wood should be able to be refinished a few times. You may be refering to a vaneer wood. The thickness on an engineered such as Kahrs is almost as thick as the 3/4 inch solid.
It really depends on the scratches and the person sanding the floors. Laminate will hold up better, but scratches and dings are "character" for real wood. And real wood WILL last longer than laminate as long as its not thin vaneer. No matter what, your floors will get some wear, even on the highest end laminates over time, so evaluate if you can deal with "character, and buy real wood and area rugs, If your plan is for the short term, and budget is tight, go with laminate and area rugs.
