Even though I'm the in-house WP guru, I have to say "Use whatever tool feels comfortable and easy to use."
Everything everyone suggested are great products Whenever I get poked by people to help make a new site (I'm currently limiting myself to family and friends who know where I hid the bodies), the first thing I do is show them the various back ends and ask them what they want to do. Then we try doing it on a couple of those apps, to see which one they click with. After that, it's gravy
Trust your gut feeling. If you see something and your heart says that is the app for you, ignore the naysayers. If you love your tool, you'll use it and write more and make a more awesome internet
