Yes, I use :<line number> very occasionally, mainly if I know I need to edit a certain line number in a file and just opened that file. But for regular use the time to type in a line number is just too long since I can't touch type numbers very quickly (when do we ever get practice typing in long numbers after all?).

I use easymotion because it's the fastest way to go from my eye spotting something on the screen to my cursor being there. It's two button presses consistently, you can't really beat that with some combination like 5j$2b, especially since that combo is different every damn time.
