Things looks pretty nifty but it's just too immature (it's Alpha, and there's a ton of functionality that's not implemented yet) to really judge. It's a good 3-4 months behind where OmniFocus is.

Looks neat, but behavior isn't all there yet. Some major stuff isn't yet implemented. Which is fine, given it's alpha, but you have to decide if you want to use a product now or wait a few months before making a decision.
