Tests on SpringBoot (TestNG vs JUnit 5)?

Question

Java

Hello, the question is a little holistic, but I need to make a decision, which is why I'm interested in the community.
A service is being developed on SpringBoot and the question was raised.
In all other products in the company, we use TestNG for testing.
But SpringBoot is tightly integrated with JUnit in the off-line documentation, I did not find anything about TestNG .. And there are not many examples on the Internet ...
Question: Does tight integration of SpringBoot with JUnit offer any significant advantages. After all, I can run TestNG tests without any problems.
After all, arguments are needed to implement another library ..
Thanks for the answers. Hope my question is clear...
