I updated my 2 year old A6 to an S8 (Premium, Gen 2). It's WAY better. I liked the A6 but it was annoyingly slow. The S8 is way better and has Android OS10 which allows split screens. Both the Amazon and Atoto websites explain the differences in the models, but if you don't need wireless Apple CarPlay then the Premium is probably the best value. It has the superior screen.
