Samus = ChanceHow existential can you get?
ZSS should beat Samus. None of Samus' aerial options can really beat ZSS if she's spacing right. The moment Samus jumps, she should be ready to eat a dash attack, because it will hit before most of her aerial options come out (nair is an exception, but doesn't have the range or knockback to be used as a reliable approach). ZSS's job is to space just out of ftilt/dtilt range, and punish anything Samus does with dash attack or grab. Samus's job is to stay grounded, and space dtilt and ftilt. She can feel free to spam if she has room, but be aware that most people should be able to PS homing missiles cold.
When the gap is closed, Samus is easier for ZSS to juggle than vice versa, but Samus can zone from below a much better. Either character will have difficulties getting back to the ground.
Samus will most likely be dying later than ZSS, and she's difficult to edgeguard, because missiles and zair are more effective against airborne opponents, not to mention she has so many recovery options. ZSS on the other hand will need to be careful, as Samus's offstage game is very strong, with a powerful spike, and a lot of offstage mobility.
ZSS can outright KO Samus before Samus can outright KO ZSS. Samus has always been weak to off-the-top KOs and ZSS's uair has been known to KO even Snake off the top under the right conditions, so Samus will need to avoid being above ZSS at high percents. ZSS will also be looking to use bair to KO at high percents. Unfortunately for Samus, most of her KOers require a little set-up to land, and they are generally less powerful than ZSS's (it makes no sense, but there you have it).
Overall, I believe ZSS should be winning most of the exchanges, and has a higher damage output. If she's patient, and spaces properly she should ultimately be able to win out over Samus.
^ because of the gimp factor... lol.
It's been a while since we've hung out. I want to see how everyone's come along over the summer and I missed you at the billfest. Ed was owning his bracket quite well (epicly funny) and lost to 2 respectable opponents (Duo's Fox and Devin's Marth). I'd like to see how you (ZSS) and Ed (Samus) fair against one another nowadays ^_^. My ganon is still wierd.... :D
