Cons
Con Resource issues
Due to the way that Streamlabs is coded, resources aren't freed up on the fly. And because of its OBS base, you have the resources usually taken by OBS, but then more resources clogged up by Streamlabs.
For example, if OBS is using about 30% of your CPU/RAM, it's quite likely Streamlabs is using another 30-40%.
Con Walled garden
Streamlabs is an entirely separate system to OBS, but using all the core (open source) OBS files. This means that Streamlabs doesn't overlay OBS - it replaces it, meaning plug-ins, functionality, theme access and many advanced features aren't as easy to find or integrate as OBS alone.
