What’s the import of the 14th and 19th Amendment? Is one more important than the other?

Both are Important

Amendment 14

All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.

Amendment 19

The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of Gender.

Neither is not more important than the other
