So you are still accessing data from a relational database when you use ORM, so you could be using MySQL, MsSQL, PostgreSQL, Aurora, or any other popular relational database, but when it comes time to access the data you use ORM in your code instead of using structured query language in your code.
From a performance standpoint I don't think you will see a huge bump, but from a productivity and workflow standpoint you will see a big difference because you have to write less code.
Ultimately its just another tool to make development workflow better. But its up to the developer and how comfortable the developer is with a technology.
A bit off topic but: Personally I feel as developers and engineers we should never take the "if it aint broke dont fix it" mentality, if we had that mentality we would never innovate or take our software to the next level. ORM is just one of many tools, look into doing things out of your normal workflow and see if it helps you, if they dont then at worse you learned a new skill.
