I've tried a bit on both 3DS and Wii U. I must say I like it, it feel like Marth but with actual kill power.
The range on his attacks isn't very good, but that's true for most character in game. His speed is amazing, and the attack power is on par with Shulk, overall very balanced.
From what I've seen, no aerials have autocancels except for the first hit of neutral air, which is a good thing since it combo very well.
The dthrow is godsend for comboing, unlike Marth's. The recovery is bad overall, but for the first frames you are invincible, with a good timing you can find several uses. DED doesn't kill, but rack up damage very well.
Flare Blade, well...is just Flare Blade. We love it.
The moveset is very good, the jab finally have some uses, and his smash are amazing powerful.
