As Wint said, right now the only people who can definitively say whether the game is better or not are still under non disclosure agreement.
And even after beta starts, the folks who will be in it still can't talk about it.
All I can say is that I like what I see in the 2.0 videos a lot more than I liked what I saw in 1.0. The Black Shroud was boring in 1.0. It looks a lot less boring in the alpha videos. Crafting was terrible in 1.0. What they've shown us in the crafting video of the alpha is a vast improvement. And it's no secret that they finally gave up and switched to a proper DX11 engine, taking advantage of modern hardware capabilities that mean a less powerful system can run the game and still have it look good.
