Depends on what character.
Recoveries it does really well on (meaning you usually don't have to follow up with anything for a successful gimp): Ganondorf (both methods), Captain Falcon, Ike (both methods), Mario, Link, Ness, Lucas, Diddy Kong (Rocket barrel method), Zelda (Din's Fire method), Kirby (cutter method), Metaknight (Dimensional cape method) Olimar, Zero Suit Samus, Ivysaur, Fox (both methods), Falco (both methods), Wolf (both methods), Wario (corkscrew method), and Luigi (Super Jump method).
Sets up for an easy cape or aerial attack counter when timed right: Luigi (Luigi Missle method), Peach (both methods), Bowser, DK, Yoshi, Zelda (Farore's wind), Shiek, Toon Link, Samus (screw attack method), Ice Climbers (both methods), Kirby (hammer method), Metaknight (shuttle loop if done right after the slash), King Dedede, Captain Falcon (raptor boost method), Pikachu (both methods), Squirtle (waterfall method), Charizard (glide and fly methods), Lucario, Jigglypuff (pound method), and Marth (both methods).
Doesn't work that great against: Luigi (Luigi Tornado method), Wario (Chopper method), Samus (bomb method), Pit, ROB, Kirby (multiple jump method), Metaknight (tornado and drill method), King Dedede (multiple jump method), Jigglypuff (multiple jump method), Mr. Game and Watch, Snake, and Sonic (all methods).
