I migrated my scrapers from Python + BeautifulSoup to Go + Colly and it was a pleasure: the new programs are impressive fast (1/3 of the time) and managing the concurrency and parallelism is a lot easier in Go that messing up with asyncio. Even the dependency management is a pleasure, no need for virtualenv or other tools. If there is something that I don't like it's the serialize/deserialize of JSON objects: you need to know the structure of JSON in advance and define in your struct. When you are scraping an unofficial API and this change silently, this can be a pain.
