Just a minor remark: Cycles is not unbiased. The term unbiased is used for renderers that do no simplifications to speed up rendering. An unbiased renderer will have a minimal amount of settings and will always converge toward a result that is as realistic as possible.
Maxwell is an unbiased renderer, but Cycles is a biased renderer that uses methods to simplify the result in order to gain speed. This doesn't mean that Cycles is not a realistic renderer. V-Ray is also a biased renderer, and the physics math behind the light ray calculations is correct, but rendering is sped up by using methods like a light bounce limit, ray tresholds, blurring glossy reflections, noise reduction and other approximations that increase speed at the expense of realism. Using the right settings, a biased renderer can yield very similar results to an unbiased renderer while offering more speed.
The Blender 2.81 master builds now include Intel's AI-powered Open Image Denoiser (OIDN). It's quite impressive what it can already do with a one-sample rendering:
BATCH OPERATIONS™ 2 is Blender 2.8 add-on and highly sophisticated data/scene manager/outliner.
The primary purpose of this addon is to cut down micromanagement of modifiers, materials, collections and other data. Apply multiple operations (add, remove, assign, etc.) on all objects via 3D view Tab panel / Floating menu / Pie-menu or Context menu. Select / outline / arrange / rename your data via file / scene / layer / visibility / text input filters on the fly and in real-time.
Ideally suited for complex models, scenes, files, whenever you need to clean, reorganize and maintain your project
This is copy paste from the website but in addition also has advanced renaming, ability to switch cameras in real-time and tons of other features.
