I use Orfogrammka along with the checks from Glavred and text.ru. Punctuation checking is especially important to me. None of the services provide this fully, but Orfogrammka comes the closest. It works well for different types of texts, while Glavred is better for dry and advertising materials, and I use text.ru for SEO checks. I respect Orfogrammka's social stance, especially that the program version is provided for free to educators.
