What kind of crisis are you thinking? Because if you're talking something like 2008 again, dividend stocks should be fine -- the market value of the stock will drop, but the dividends should remain stable. In fact, the smart investor
loves those times -- it's a great time to accumulate assets.
If you're talking something like a collapse of the entire economy, then yes, tangible assets like gold and real estate are much better. It's not impossible, but I don't know if it's especially likely that's going to happen....
That said, I do invest in gold/silver and real estate as well for various reasons. I also invest in dividend stocks for other various reasons. They all have a place in my strategy.
I haven't done much research on emerging markets, but isn't that a very high-risk/high-reward investment? For now, while I'm still stuck at my job and not yet "rich" (by my conservative definition) I'd rather mitigate my risk and have some control over my investments -- I plan to be successful and well-off, I'm not just hoping that I get lucky and one of my investments' value goes through the roof.
(I'm not criticizing and I didn't downvote you. I'm actually interested to hear others' investing strategies, maybe I can learn something new!)
