Revelations is probably better. Kid Icarus is amazing and I like a more Nintendo game, but Resident Evil pushes the 3DS in terms of content and graphics. It has a full 10+ hour campaign, plus challenges, achievements and tons of unlockables. Then it has a co-op raid mode which can last dozens of hours as well. It also has fantastic graphics and is an incredible cinematic experience. Kid Icarus is great though, it quite a lengthy campaign, plus multiple difficulty settings that actually change what items you unlock and secret areas, achievements, online multi-player and tons of different weapons and abilities. Both are literally both leaking with content. Resident Evil Revelations has better graphics though, but Kid Icarus also looks incredible and uses the 3D effect incredibly well.
