Default How stable is Xposed on the GS5?

I just rooted with Towel root and did all the goodies (debloated, etc). I'd like to use Xposed for Gravity box or Wanam. I noticed some threads are complaints about the phone acting up after installing the framework, others say it's module associated.

Curious to how stable the framework is. Is anyone experiencing anything without running any modules, or with Wanam/Gravitybox?
