Screen Studio is described as 'Create enhanced macOS screen recordings with mouse smoothing, zoom on clicks, cinematic motion blur, editable backgrounds, and support for webcam, mic, and sound' and is a Screen Recorder in the video & movies category. There are more than 50 alternatives to Screen Studio for a variety of platforms, including Mac, Windows, Web-based, Linux and Google Chrome apps. The best Screen Studio alternative is OBS Studio, which is both free and Open Source. Other great apps like Screen Studio are OpenScreen, SimpleScreenRecorder, ScreenArc and FastStone Capture.
I'd say Loom is a bit less for studio quality screen recording, and more for fast shares, tutorials, etc. (I've used both Screenstudio and Loom) Screen Studio is excellent for making things like product tutorials, youtube videos, voiceovers, etc. Loom is excellent for teams to share things async.
