Speed depends on how the boards are connected: parallel, serial, and when serial, clk speed matters too. IL9341 performance with Standard Espruino and Pico are for sure comparable. If they are not about equal, something with the setup is wrong. It also depends how many colors and what font is used. I felt it is about the same.
