Eastsheen are still active like Rubik's. They're probably both well known brands in the speedsolving world. But speedcubers have their own preferences for hundreds of various similar designs that have been released in the past decade.
ES might not be widely used by cubers here but it might be more accessible than some of our favourite cubes. Less than 30,000 people have competed in WCA competitions over the past decade when I checked a few months ago. And over 300 million Rubik's cubes have been sold.
It's not that easy for local retailers in the Western world to stock "popular" puzzles, from a speedsolving perspective, when they allegedly infringe upon patents. National distributors have a limited selection and are heavily influenced by some of their suppliers.
It'd be interesting to know how many puzzle are sold in Asia...
