The only best on this "R4" card is the box.
Looks the Box is more worth as the flashcard.
Each supercard works better as a R4 card.
If you want a realy good Flashcard buy a DSTWO!
I can only say, see what is happen as the R4 team
steal the firmware of Gateway.
On which Firmware works this card on your 3DS?
Work the R4 card in the future on a newer Firmware?
Play the card also gba roms?
