I bought gw after I tried CFW. I prefer gateway over cfw. Gateway is much more stable than CFW, unlike CFW, Gateway doesn't need to have nightly build constantly made and pushed out just to please everyone. Gateway is the original CFW, the red card is just a dongle to enter emunand. CFW and gateway can't boot past 9.5 on the N3ds because of nand encryption issues. I also own a sky3ds card, which isn't all that amazing. Gateway trumps both cfw and sky3ds due to being able to load .3ds and .3dz files along with CIA installation, cheat menu support, and soon to be in game cheat menu.
