Probably not. Varnish comes in two flavors, poly and non poly, poly being
the more damage resistant of the two. For a coffee table either should offer
sufficient protection but if it gives you the warm and fuzzies there isn't

Superlatives such as diamond hard and ultra tough are advertising hype. No
varnish is hard as diamonds and ultra tough compared to what?
Over the normal life of a coffee table any differences in wear ability
between poly, non poly, ace hardware brand, min wax brand, and ultra tough
diamond hard brand will be hardly noticeable..
