Should I upgrade my forum XenForo 1.5 to Xenforo 2?

[OnaDavney]

As I know then XenForo 1.5 is no longer supported while I am having a Xenforo forum using 1.5.x, I think I should upgrade it to Xenforo 2 but not sure it is better than Xenforo 1.5 or not. Can you guys give me any advice?

Definitely if its no longer supported, you want to continue to receive security updates, new features etc. I don't use Xenforo personally but I can't see any reason you'd want to stay on older software thats no longer supported.
