I don't see why not the switch ones. They cost usually the same amount as their non-switch alternatives and give the easier ntrboot experience and if used as normal ds flashcard they don't need to worry about the switch.Thanks, do you have a link to one? One that works as a normal DS flashcart right away (not one of the switch ones) and is also very compatible with ntrboot (backup firmware is available and easy to find etc)?
