Arc Studio Pro and Highland are very different. Highland is macOS only and more of a minimal editor built around the fountain format (think markdown for screenplays), and has a very unique formatting UI. Arc Studio Pro wants to support the full process and offers collaborative editing, automatic versioning, feedback management, outlining and visualization tools, etc. Both apps offer a free version, so give them both a try.
