We've had both and with my husband's business the Reflex spray in liner had been the best. He's a brick layer and the sand and cement really gets in under something just laid in the bed. This truck has had this for 10 years and the only place there's any bad wear is at the end gate from sliding pallets of brick and block in with fork lifts. To each their own a the saying goes. The quality and durability I'd the spray in stuff I'd VERY dormant on surface keep and the care taken by the installed. That's where the big issues are. Ours was out in 1/4" thick overall. In our business inside fender dents are a cost if doing business. Poor old truck. Mach loved but ride hard,a lot.
