Sigma AI vs Appen: the short answer

On pay, Sigma AI is benchmarked at Not stated; Madrid transcribers report ~€7–€9/hr (Glassdoor) and Appen at $2.40–$100/hr; CrowdGen experts up to $450/hr; their boards do not state enough rates to tell which pays more, so compare against your own hours.

Both are microtask crowds, so the barrier to start is similar: open to anyone after a short qualification, no degree or experience required.

Both hire for Multilingual, Transcription & Audio, and Data Annotation; Appen also covers Robotics Data and AI Evaluation.

Bottom line: what we know does not separate these two on pay or on how many people they accept, so choose on the specific work each hires for.
