Things to look for:
HDF vs MDF High vs Medium density. HDF is harder, as well as being more water resistant usually.
Sealing edges. The edge instead of just milled is sealed. Some use a waxy coating that with time seals to the adjacent edge. Doesn't make them water proof, but increases the water resistance.
AC rating. 3 is typical, 4 is heavy use, 5 is commercial.
Avoid high gloss surfaces. They show every ding.
Avoid really light tones. They show dirt. Avoid really dark tones. they show damage. Look for a 'red oak', or medium tone that is close to the colour of the substrate.
Most stores will give or sell cheaply samples. Take candidates home and sand through the pretty layer to the underlayer. You will see what you get.
If you are using it throughout the house, consider glueing the edges near places that have high water hazard: Anything in a bathroom, entrance area especially if you are in a snow/mud climate, near sinks.
Generally I wouldn't use laminate in a bathroom or in a laundry room. Instead look at loose lay sheet vinyl. You can float it, or glue it down. Floating requires the same edge clearance system as laminate. In a wet area caulk the edge so water can't sneak around the edge ofthe floor an wreck your subfloor.
