I've used Coda for a few years, during which time I started using Sublime + wbond's FTP plugin. Coda is still crucial to my remote PHP freelance workflow. For remote work, it's a much more polished experience when dealing simultaneously with multiple active/live projects.

Sublime FTP's experience can improve slightly when using it in mirror mode, but in practice I've found issues with very slight time differences between my local computer and the remote computer, which can cause unnecessary or possibly dangerous syncing.

Can't really think of any Coda negatives other than lack of git integration. I generally just keep an SSH open to commit anything.

Edit: nvm, it does have git integration. I'll have to try it out.
