To enable the developer extension, type the following into Terminal:

defaults write com.apple.Safari WebKitDeveloperExtras -bool true

Once you restart Safari, you should see an “Inspect Element” option if you right-click anywhere on a web page. So far, I am very impressed with the interface and debugging options it provides, along with the overall speed of WebKit browsers.

Having used Coda the past year and a half, I must say the features I like most are the way it handles CSS and PHP auto-scripting, the integrated FTP management system, the seamless integration of SVN, and the built-in help books for HTML, CSS, Javascript and PHP. The color coding for scripting is also a huge plus as I find the colors to fit perfectly with the code. Quite simply, it’s extremely fluid and somehow manages to make coding seem effortless and fun.

Espresso, on the other hand, is only a few months shy of being released from beta and I’m not sure it can win me over just yet. I’ve become quite comfortable with Coda and think it will take more than another code editor/FTP manager to get me to make the move. I do like CSSEdit, which is available from the same developer, MacRabbit, but I’m equally as happy with the built-in CSS editor in Coda (even though I find hand-coding CSS a bit more satisfying)

Text editors for writing code are very user sensitive and can make for quite a personal dilemma. But whatever your style is, feel free to give them both a shot as they are both VERY good at what they do.
