Both Samus' are good at both close and long range. But apart from that they are completely opposite! Power Suit Samus is a lot stronger at a distance, where as Zero Suit Samus is a lot stronger close up! They appeal to completely different players styles!
They're not designed to be completely defensive, so they have small jumps that limit their ability to recover from huge attacks. This is more of Power Suit Samus' problem more than Zero Suit Samus'.
Long range attacks are Power suit Samus' speciality, and they can be used in conjunction to create devastating combos even at a distance. This makes for great ways to initiate the battle, especially considering that they are very good at setting up smash attacks immediately afterwards. In multiplayer battles or when you are facing an opponent that's better than you, try to use long range attacks to avoid taking damage. The charge shot is a nice knockout move, but don't rule out the super missile.
Don't let her long range advantages keep you out of melee combat, she also has attacks designed for close range so she's more of a rounded character. Use Screw Attack if you get attacked from above, and set traps with Bomb. Samus' upward smash is very good for dealing damage, and her side smash isn't too bad at knock-outs. Instead of using her downward smash, use the standard downward attack for more damage and knockback. Use the grapple beam a lot as it's your longest-ranged melee attack. It can keep other fighters from getting close to you and it assists your long-range game.
Standard Attacks

|---|---|---|---|---|---|

|
Arm Cannon Jab | Damage: 3%, 7%
Urgency: Low-Medium Punches then jabs her arm cannon. Useful to knock the opponent back to reset spacing and allow range to camp. Can also cause tripping at extremely low percents. |

|
Samus Roundhouse | Damage: 7-8% Normal, 10% Down-angled or Up-angled
Urgency: Medium Does a spin kick. Can be angled, and for non-angled, the move does less damage at the end of the foot. The same use as the neutral jab combo, but with more range for the non-angled variant, but with less damage. |

|
Suit Slice | Damage: 13% on grounded opponents, 12% on aerial opponents.
Urgency: Low-Medium Samus holds her leg up and brings it down like an ax. This move looks and acts like a meteor smash while the opponent is on the ground, but if used on an aerial opponent it will launch horizontally. Surprising knockback, but slow to start. A good anti-air move if you anticipate a short-hopped aerial or landing aerial. Also good for edgeguarding easy to anticipate recoveries such as Link's. |

|
Ground Blast | Damage: 14%
Urgency: Medium Samus points her arm cannon to the ground then blasts it with an explosion. It has a small amount cooldown but has great knockback. Very good for hitting opponents that get too close, but has poor range, so otherwise forward tilt is probably better. |

Suit Boost | Damage: 10% at the beginning, 6% at the end.
Urgency: Low-Medium Samus charges forward with a small rocket boost. Has surprising range, going about 1/3 of Final Destination, but has low damage for the most likely hitbox and average knockback. Could be good for pressuring a shielding opponent when used together with homing missiles, as long as you make sure Samus will go behind the opponent to be immune to a shield grab. Then follow up with a down tilt or two and you'll be likely to shield poke. |

Grapple Beam | Samus uses her grapple beam to zap opponents. This move is infinitely useful as it is long ranged, keeps opponents away from you, prevents them from recovering back to the stage and even KO at high percentages! Use this as much as you can, as it doesn't even suffer from landing lag! |

Final Smash
Zero Laser: Samus fully charges her laser and unleashes a powerful beam with maximum power. This beam, although it can do a lot of damage, is slow and can be jumped over. After this, her suit will fall off and you will transform into Zero Suit Samus. To become Samus again, use Zero Suit Samus' Final Smash.
It has a weak point which can easily cause your death: While you are transforming into Zero Suit Samus, everyone who has a life remaining or having saved from the beam have enough time to charge an Smash against you, as you are not invincible while transforming and you cannot even use your Shield. Be careful with that if you use the Zero Laser!
