IIRC, and understand the theory correctly, I believe your best chance for survival is a spinning supermassive black hole. I think that's the one that might not spaghettify you. I know you want supermassive, just can't remember if you want it spinning or stationary.

If you can survive it, you'll end up at the end of the universe within your own lifetime, due to time dilation. Possibly almost instantly from your perspective. Not sure what you'd do at that point though.
