What’s the point of using a self-owned certificate with REALITY? How does it differ from Trojan+XTLS-RPRX-Vision?

As mentioned in the title, I’ve seen claims that using your own certificate with REALITY performs quite well. I’d like to understand the differences between this approach and using Trojan. Furthermore, how does the anti-blocking capability of REALITY with your own certificate compare to using other certificates? Which one is more effective?

如题，我看到有人表示reality使用自己的证书效果不错，我想知道这样做与使用trajan有什么区别？reality使用自己的证书的抗封锁能力与使用其它证书比谁更强？
