Depends what you consider much traffic, I suppose. I'm used to fandoms that haven't seen new canon material in over a decade...
With either place, you're still going to want to advertise on the various DW/LJ comms and such, just as you do now. You're going to get more people randomly finding you on FFnet, but... yeah.
FFnet also randomly deletes formatting, so that's always fun.
AO3 is rumored to be adding subscription stuff soonish, which will help. I've toyed with the idea of adding the non-smutty parts of S&S to FFnet just for the random readers myself, though. With a link to the full version, naturally.
