I use a combination of Espresso and TextWrangler. TextWrangler is more if I need to do something quickly and Espresso is my CSS/HTML go-to app.
Both do, actually. Espresso is more for full projects while TextWrangler is for individual/quick changes. Also, TextWrangler is free while Espresso is $79. I still think it's worth it but you can try both out.By any chance do anything of these have FTP integration?
I use Coda, but it's more of an all-in-one type of thing, as opposed to just a text editor.
Try Sublime edit
