If you prefer visuals over table here is a comparison between price and range (as stated by the board companies). I have excluded all boards that were released prior 2017 to keep the chart clean:
I have highlighted the most established companies Boosted and Evolve in orange and blue. It´s quite interesting that Evolve is claiming the top range board still in 2019. However, the competition is quickly growing, especially from young and agressivly priced Chinese boards. I have highlighted these boards in red. They all were released in 2018 or 2019 and usually trade below USD 1,000.
