Answer:
I think a Constitutional Monarchy is the better form of government because they have rules where that are kept within its limits and are elected by its citizens. On the other hand, Absolute Monarchy gives the leader complete 100% power and has no limits. This basically means a leader you don't even know could just grab you middle of the streets and throw you in jail with the reason of "I just feel like it" which is Absolute Monarchy. There is no need for such power there is a reason why the American government is split between multiple parts to avoid absolutism
Sorry if the answer is too extreme heh
