There's a variety of vore, so I can't speak for everyone, but what I can talk about is the stuff that's probably safest for newcomers.

The vore I'm into is soft as soft can be. It's consensual, people are swallowed whole, are alive, comfortable, and safe in the belly, and later they're magically out somehow and I'd prefer to not bother with the details of exactly how that happened.

I like the closeness of it. The idea of trusting someone enough to eat you and know you'd be safe, or of them trusting you enough for it gives me warm fuzzies. Plus the 'being in the belly' part just strikes me as a lot like a big weird hug. And I like hugs too!

...The harder vore, with nonconsentual stuff, violence, and death, is not my cup of tea. I think that fetish is basically about power dynamics, but I'll leave it to someone who's actually into hard vore to discuss it, if they want to.
