A pretty critical point: Obama used Executive Orders because in part he had a Congress that, courtesy of Mitch McConnell, stated openly that they had no intention of passing Bills on the President's behalf, even if good. That the way to make him a failure was to "do nothing for him". That left Obama with little option but to enact Executive Orders for many things. And with that being said, he still managed to sign less than Bush II or Clinton.
Trump on the other hand has Congress and Republicans firmly in his control, who've shown themselves to be fully "pliant" (or "spineless", depending on your perspective of the world) of all Trump's desires, so Trump has no _need_ of the Executive Order other than to make a statement, "Look at me, I'm the boss. Why would I act like I need approval from Congress?"
There's a distinct difference.
