I haven't used sublime that much so I can't really compare them. RubyMine has helpful things like auto-complete, cmd+click to see function/class code (works for things like locales and gems too), generators without going to the command line, and a console for autorun unit test results off the top of my head. On the negative side its a memory hog and costs money (though they seems to have sales every once in a while so you could get it slightly cheaper).
