Coda 2 comprises all you would expect from an IDE: it supports multiple languages (including all the standards); it performs autocomplete of project names, as well as language functions; it supports SVN and GIT; it has good support for plugins (or you can write your own); it has a configurable editor; and it has a built-in preview.
Pro Multiple environments
Pro Dynamic values
Pro Many extensions
Pro Option to create a new API

Pro Regular updates

Cons
Con Defective UI
There are several things in Coda that simply don't work, and never have. For instance, the root directory for your local and remote files is simply not honored. For every project, you can specify the root directory for its files. But when you open the project in Coda, it doesn't go there. The file browser just shows whatever the last directory was that you were using, and will write files to the wrong place. Thus, it defeats the purpose of setting the home directory in the first place.
Also, splitting the editor doesn't work. If you've done any programming, you know how important it is to be able to view two files simultaneously. Coda fails to do this, with a bizarre insistence on making the two panes dependent on each other.
Con Support for Mac and commercial use only
Coda 2 is only available on Mac (even though that does make it a native app, meaning its much faster). Coda 2 costs $99 after the 30 day free trial is up.
Con No XDebug
If you also write PHP, there's no XDebug support available.
Con Restricted and unstable Web-View
Javascript Events can cause crash or will not be recognized.
Con Proprietary, closed source software
Not free and open source.
