pol doesnt have a high adhesion property cause it sits on the in layers when laq soaks and each layer dissolves into the one under itpoly doesnt scratch as easylaq dries fasterlaq has a more refined look IMO

If you are looking at a great finish with the burn-in properties of lacquer and a tougher finish then poly, take a look at conversion varnish (odor similar to lacquer). It is a two part solvent based finish that dries very fast and is considerably more durable then either lacquer or poly. It is the only thing I will use in cabinetry.
Lacquer is a burn-in finish with a final thickness that is less per coat then poly. As cabs4less says, poly is a film finish that layers on top of the previous layer (tougher to repair). 3 coast of poly is thicker then 3 coats of lacquer.
You can get water born lacquer – I have tried it with limited success – that doesn’t have the smell of solvent lacquer. A water borne poly (little or no odor) will dry pretty fast enabling you to complete 3 coats in a day without any problem. The conversion varnish enables the same thing – 3 coats of finish in one day.
Poly hides scratches better because of its flexibility. It can expand and contract more then most other finishes.
