Qi's the only one I listed who has only one map rated 4+ and that is because I suspect players that don't like Qi may have deliberately rated his maps low. The others all had multiple maps rated 4+. Feel free to write a bit about your favorite mapmakers on this thread and explain why they are a great mapmaker.
At Richard's request, I wanted to add another mapmaker. He has made only one map but it is beautiful.
