Typeless has the broader feature set today. It runs on Windows, supports 100+ languages, offers built-in translation, and provides a free allowance of 8,000 words per week. Its paid plan is priced the same as Rutta's listed U.S. subscription when billed annually or monthly. If translation, Windows support, or maximum language breadth is essential, Typeless is the stronger fit.
Rutta is the alternative for people who want voice to do more than replace the keyboard. It is designed around a more open writing loop: think, say, see, and think again. Choose it when you want to get the whole thought out before editing decides what the thought should become.
