I use TextMate for most things, Espresso for working on HTML mailers and (some) static sites, XCode for iPhone/iPad, and Eclipse for my most hated projects (Adobe Flex/AIR mostly. I don't hate Flex, I just hate Eclipse). I use Inconsolata font at 14pt and a modified Monokai theme (with darker background) whenever possible. About once a year or so I decide I'm going to switch to vim. I spend about a week getting my vimrc and plugins set up and use it for a couple more weeks, before I eventually get sick of keyboard navigation and NERDTree and go back to TextMate. I know that with MacVim I get things like scrollwheel support and mouse navigation, but if I'm using those anyway I might as well use them in TextMate and get back my tab triggers and other shortcuts. It's always good to brush up on vim once in a while though, since it often comes in handy when you need to edit config files on a server or when you are collaborating with a developer who uses vim exclusively. I also wish TextMate had split panes and some of the keyboard shortcuts (o, O, I, and A come to mind), but overall my productivity is better with TextMate.
