Trump has stated that his biggest regret from his term is that the people he appointed to various positions, while quite competent and/or experienced, would push back on ideas or plans he proposed. In other words, they weren't loyal.

The difference between this term and his previous is going to be a much stronger focus on making any position he can appoint be one that doesn't tell him no. And it looks like many of the positions he can't (the senate and likely the house) are going that way too. That, to me, makes him represent a meaningfully larger threat to the balance of power in the US than his previous term.
