Hi there, well the big advantage is of course the new colour, it's better in every way!! π no, just kidding - the 2 shapes are exactly the same, for 2020 and 2021. The previous STB was also a very good board, but had some issues on spin-out for back foot heavy riders - the newer 2020/21 shapes are a great update and appeal to pretty much every rider for both flat water and waves (obviously a u pure waveboard or free ride board will be better in each of these conditions if you are only planning to do one of each). Good luck!
