I'd side with then, constructs don't seem as durable as they use to be.
Compare Hal shooting a hole in Amazo or when he went Crazy and took out the JL
To modern times where his constructs break on contact with Darkseid not phasing Uxas and any Herald tier can destroy his constructs pretty effortlessly.
I think GL's, primarily Hal were more versatile back then. Transmutation, vast energy control, teleportation, invisibility, intangibility, etc... They can basically do anything. Today, you just don't see that.
