New - definitely. Improved... it depends. If you think it's improved, fair enough, but this is your opinion. Not everyone has to agree. For example I think, it's got more features, but is lacking regarding the interface and usability. Overall, I don't consider it "improved" enough to adopt in everyday development.

Not spending time on completely learning how to deal with an inferior (imo) tool, gives me more time to learn things which matter to me. So it's the exact opposite of "learnt nothing".
