Is it worth updating CPF to 2.4 if 2.3.6.81 is working well?

I’m currently running CPF 2.3.6.81 and all is going pretty smoothly. My question is a simple onoe: is it worth it to upgrade to 2.4, especially since the upgrade process isn’t smooth and there are a few bugs in the latest version? What is to be lost in staying with the penultimate version.

thanks
