As @Hudson555x told, OBS is fully customizable.
Paid softwares are better in most of the categories, but in screen recording actually OBS is the best, Bcz it is totally customizable and has very helpful advance feature. The problem here is that you need to learn it, and if you learn it, you can do green screen, color grading, cropping, etc. in OBS only, So that you don’t have to do much in post production. And it is also used by many professional youtubers like:- Blender Guru, Justin Brown, SomeOrdinaryGamers, etc.
