I'm a little fanatical about finding the ideal code editor. I've used Sublime Text, Coda, Espresso, BBEdit, Komodo Edit, and quite a few more. Chocolat is the one I keep coming back to when I need to get things done. Its autocompletion/code-hinting isn't quite as good as ST2's or Komodo's yet, but there was a huge improvement in 1.5, and it's getting there - it's actually better for CSS and HTML than ST2, not quite as good for JavaScript and other programming languages. The mixin model using Node is brilliant -- just wish a few more developers were taking advantage of it, but that being said the Emmet mixin is superior to any other Emmet implementation that I've used. And though it does have its quirks and bugs, there are far fewer, I think, than in ST2 (or the ST3 beta.
If you spend a lot of your time writing code, this is at least worth a try.

Beautiful UI coded for OS X exclusively is the only advantage I see over it's many formidable competitors which are either open source at this point (TextMate), free (TextWrangler), or are very scriptable/customizable (ST2/3) with lots of examples to get you started with their huge customer base and dedicated users.

Besides the beautiful UI. I do not see any advantages over existing editors. Not lighter on resources for one even though OS X native and I know it is still being developed and I'll continue to watch it and try it out every once in a while but I think development needs to be focused. It would benefit the developers and their users in the long run...

I like the app, will watch development, and keep faith it may one day become a leader in a tough class but I think the devs need to rethink their "cover every language and compete with the big dogs" approach and instead focus development on a few languages/aspects instead of doing everything "okay, as well, or almost as well" as some other bigger named editors that have been around for much longer. Do a few things better than the rest, and move on, pickup new users in the process. Make it more customizable than other text editors, provide (more) examples to make up for the lack of user base.

Just not worth the money when you compare it with the few examples that lead the class like BBEdit/TextWrangler, TextMate and Sublime Text 2/3. Lovely UI, I hope the code underneath the UI catches up, really want to like this app more than the others but I can't once I start using it.

I used to keep a close eye on the development of this application, participating in the open beta program and asking questions of the developers. Unfortunately I was very unimpressed with the process, and the developer made it clear they were uninterested in supporting many user needs, such as code comparison or file diff. That's a pretty foundational feature, in my opinion!

Ultimately TextWrangler is more capable in many cases, and while not remotely as pretty or modern, it can actually do what I need. And it's $49 cheaper. Not sure how Chocolat is intending to compete with that.

SCRIPTING—this is huge!
