Depends on your floor (and what you're trying to achieve).
If you have a suspended wood floor, and you want to hear the sub's bass output, not the room and floor rattling, use something that isolates. The Auralex SubDude is a nice option. A cheap, but not quite as effective, alternative is $1 hockey pucks. And then there's everything from isopods to sandboxes.
If you want to hear your room rattle and feel your chair vibrate, as some ( esp home theater guys) do, then couple the sub to the floor with spikes, etc.
If your floor is concrete slab, then the effects of either won't be as pronounced, and I think most find cones appropriate here, though isolation has been said to reduce floor vibration a bit here too. Again, depends what you want.
I've tried the pucks and DH cones and Pulsar points and even Aurios under my RBH subs. They all helped in slightly different ways, but I'm using the inexpensive pucks at present. I may try the SubDude next. Then again, I like bass that's extended and tight and non-intrusive, and I also use a Tact to equalize and eliminate room nodes.
I had an audiophile friend over a while back and he thought my bass was anemic. He didn't like it. The bass was too flat. Me, I thought it sounded great, but it takes a while to get used to flat bass as we're so accustomed to the extra room-induced boom.
