Seriously, you are constantly having meetings and doing boring shit that you must because that is expected of you. Sure you get the title and the palace, but unless you’re in Swaziland, Brunei, Oman, or Saudi Arabia you have no real power. I’d much rather be Prince, since you have all the benefits from being Monarch but none of the drawbacks. Of course, many would disagree with me.
The only thing worse than being a King is being a Pretender. Seriously it’d be all like “well I WOULD have been in charge if it wasn’t for that damned commoners wanting a Republic.”
