Microsoft Expression Studio 4 Web Professional

Hello everyone, has anybody here heard about Microsoft Expression Studio 4 Web Professional and also have a feel of it. I want to know if it does wonder more that the usual adobe suite

it a great development suite, starts up faster that most of its adobe counterparts and uses less system resource, but personalty i still prefer the adobe suite and use Dreamweaver for all my HTML and CSS developments, i think it all boils down to personal preference.
