What 3d Render Software/Plugin is the best for quality and speed time render results?

I'm just beginner and have watched full video from well known 3d Designer "Blender Guru" about 3d Render Engines but even after that , it's hard for me to chose between this huge variety of 3d Render Engines. I feel like Corona is the best for quality images but in the same time it uses only CPU so it's far not the fastest. So, I would greatly appreciate to hear expert opinion on this theme)
