I get this question a lot, and yes epoxy is stronger.
Not only is two part epoxy stronger, it also sticks to more types of materials. Wood glue is very good at holding one piece of wood to another, assuming that the woods are not super oily. Epoxy can be used on so many different materials that it’s impossible to name them all.
A short list would be metal, wood, shell, plastics, and cloth. If you are looking for a very strong bond, and the ability to bond several different types of materials together, then two part epoxy is your winner.
My running joke about two part epoxy is that it will bond anything together short of water and air.
