Whats the best streaming/recording software?

OBS for sure, you'll get everything you need, for recording and streaming. If you're looking for editing programs, I'd recommend Sony Vegas for a more professional look into editing, or Camtasia for a more.. Drag and drop feeling of editing..

Depending on your PC setup I have been able ot get better quality with OBS vs Streamlabs. Not sure why but i can get an almost perfect picture with 1080p at 60 FPS on OBS.

Got a friend who usually streams overwatch and he always use OBS I should ask him his configs.

The games - FBX recorder and streaming - OBS. I will help you.

For recording me I use NVIDIA GeForce Experience. It allow me to record 5 last min ^^

Definentely OBS Studio for streaming, because of the many plugins.
As of recording videos, i would strongly recommend Shadowplay. Your FPS doesn't get affected to much.

One of the best programs to make streaming is OBS live stream, super easy to use and is very much content on the internet to learn
