What is the difference between the R4 and the supercard ds one?

What is the difference between the R4 and the supercard ds one? I am going to buy a ds emulator. But i need some info on which to get; the R4 or the supercard ds one? what is the difference anyway? i don't care much about price difference, all i need is an emulator that can play full games with great quality, and is easy to use. Which do you reccomend? Hi. All DS flash cards are pretty much the same. They all play DS roms and homebrew applications. The only differences are the interfaces. Between the two, I would definitely go with the R4 as it's way more popular and has more support.

ds two card, ds two supercard, nds r4, ndstt
