which is the best server My SQL server or SQL server

Hello everyone, I’m new here and I am preparing for my first installation of Word Press Org.
I do not have much experience on My SQL server, and i know sql server a little bit.
I’d like to ask if it is better to use MySql, because it’s supported for Word Press, I would not install SQL server and then find out that it supports the latest installation word press com, or the latest version is just a mapping of the version runs on the MySQL server.

Thank you, I apologize for the lack of language practice
Thank you,
greetings
