One advantage for epoxy it’s better for detailed work. Liquid nails could get messy.

In my experience, epoxy has worked for me better than liquid nails. I don’t even think of them as interchangeable. I’ve had failures with liquid nails. Never with epoxy unless I screwed up the mix or something like that. If I want/need something in a caulking gun tube, I go to Loctite PL Premium.

Liquid nails is a polyurethane-based adhesive. It has completely different properties than epoxy, which is a resin-based adhesive.

They each have their uses.

Apples and oranges.
Epoxies are high quality versatile adhesives capable of massive holding power over long periods under extreme conditions.

Liquid nails is a construction adhesive.

I wouldn’t go to sea in a boat held together with liquid nails.

I don’t mean to be rude here but there is a huge difference.

New kid on the block for construction bonding agent.

“This 100% waterproof, low odor formula is designed for both interior and exterior projects, and is water, frost and heat resistant from temperatures of 0-120°F. It is solvent free, has a quick cure time, and can even be used on damp or wet surfaces. Initial Grab So Powerful It Quickly Holds Heavy Items – Even On Vertical Surfaces”

Guys are using it to direct bond pink foam board to concrete, or block basement walls, no studs needed, then another layer with electrical, and plumbing chases cut into it, then drywall directly to the foam. Passes code without a second look. If Granny can lift a piece of foam board, and cut it, she can do her own basement flip.

I don’t think of epoxy so much as an adhesive as a mechanical bonding agent. Take something like E6000 and put it on pretty much any surface and it’s stuck. Put epoxy on smooth steel, glass, etc, and it pops right off. But when it’s got something to grip to, epoxy holds fast.

Am I off base?

I believe you are Rich. Have a look at this article.
Construction adhesives and epoxies are so different that they should hardly be spoken of in the same sentence (IMHO). They both have their place but very different.

....... I have used a lot of epoxy in my time building boats.

If you are going to just base it on sticking one thing to another, construction adhesive is probably the best choice in situations where it will work. The difference is there are tons of things Epoxy is good for and construction adhesives would not even remotely work for. Like others have said Epoxy is a resin and poly construction adhesive is just an adhesive.

What are you trying to bond?

I couldn’t imagine trying to edge glue two planks together with construction adhesive. The thick goo would leave an ugly crack.

In wood turning epoxy is the perfect vehicle to carry either wood dust, shavings or color pigment into a void because it does not add a color of it’s own. I can’t speak either way for construction work or basement conversions.
