The board is great and you should try it, it has a lot of cool stuff that you can expand ( i added chamber temperature monitoring, touch screen and stuff).
I had some issues like E0 Dir pin had no voltage on the board, that is the reason why I remapped the pins for E0 to use E1 connector. it does not mean that you will have the same issue.
If you intend to use drivers as stand-alone you will have no issue at all, but if you want to use them as UART only Y axis will work out of the box all others will trigger TMC connection issue and will show failed when requesting M122.
if you need that you will have to add a jumper wire from Uart on the drivers to an interrupt enabled pin and map it in pins_FYSETC_F6_13.h it's not really hard after that all works fine.
