The special contains 4 short stories, with time-skips between them, rather than a more cohesive storyline the standard episodes provided. It also overdoes flashbacks a little bit, making the whole thing feel a bit half-baked, like a compilation of skits that didn't make it into the main show, diluted with some filler content. Other than that, it's still more Wataten, so if you like the formula it's worth checking out. The gags are pretty creative and amazingly enough, the show still steers away from the fanservice these extra episodes so often are about. It underlines the positive surprise I had discovering that it might be ashow about a lolicon, but not one for lolicons – which is a subtle distinction that makes all the difference. ;p
