I am a Lucas AND Ness user so I guess I see them as very close. One main thing I wonder though, How come everyone says that Ness' aerials are better than Lucas'? I find this false. Ness' Fair is very good, but Lucas' is not only decent on the damage (more so than Ness I believe) but at lower % it can be combo with itself or other aerials with relative ease. Ness' spike is amazing, yes, but Lucas' Dair can be used very efficiently with short hop techniques and can do 20 damage (far more than any other Ness aerial) , also it is a spike! Ness' back air is powerful, but Lucas' is a useful spike and has a wide hitting range. And as for the Uair, they are both very similar so I have no comment. I agree, Ness has beastly aerials but I also believe that Lucas has just as beastly ones.
Another topic I wouldn't mind touching base on is the Smashes and Tilts. Ness, overall, has terrible tilts and a very slow Fsmash. Also his U+Dsmash's are not that useful in anything other than starting off a combo. Lucas on the other hand has amazing tilts, especially Ftilt. Lucas also has a fast, useful Fsmash. Furthermore, Lucas has an U+Dsmash that, when timed right, are amazing assets to his arsenal.
A third topic I can touch on is Throws and Recovery. Throws go to Ness, even if Lucas has more range with his grab. Recovery. Lucas, Lucas, Lucas. Lucas' recovery is farther, faster, and not able to be interrupted. AND he has a grapple. Also with Zap Jumping at his arsenal, you better hope to knock Lucas out of the play area if you want to kill him.
Conclusion:
Lucas.
Ness is amazing and when the situation is right he is better than his blond haired clone (of sorts.) But for overall purposes, Lucas.
