I used to feed raised, but don't anymore.
I had a real nice, handmade wooden feeder that then-DH made. It held stainless steel bowls, but there was a platform underneath that, no matter what I did, would get all slimy from the water being slopped around.
I also read that study that suggested raised increases bloat risk, so that influenced my decision to go away from it, too.
I'm considering going back to it though, now that Gunner is getting older. He's pretty tall and it has to be a little uncomfortable for him to bend down so far.
