Upon further review, I shall opine that your company's product is better than Google Maps, but inferior to Baidu Maps. I like the fact that you provide subway station exits, including those on newly opened lines, but Baidu offers far more detail. Regarding professionalism, this is not a significant concern with respect to mapping companies unless there are ethical issues at stake. Feel free to explain why your company is more professional than Baidu; we are all ears.
