I have never tried it. It never looked appetizing to me.
Wise decision, you'd probably get more enjoyment from eating a lump of lard.
Re-reading the posts about corned beef and spam makes me wonder what Northern Hemisphere corned beef actually is.
There's two kinds of corned beef available here. One that a butcher will make himself, a nice bit of brisket cured in brine with additional flavour added by the butcher in his own "secret" recipe. It's good, slices well and still looks like beef, it's ideal for a sandwich.
Then you have the off the shelf stuff in a tin. Which is a sort of compressed mash full of salt and fat and I doubt that there's very much actual beef content. It's cheap and OK in an emergency I suppose, but that's about it.
