That is a hard question to answer. From my 8 days of trying it so far, I would say it is better and easier than non-cloud mining (although I have never actually done any non-cloud mining). It all depends on how you interpret the results I posted in my review at http://www.impulsecorp.com/strike-it-rich-with-bitcoin-cloud-mining (I updated the results yesterday, and they are still earning at the same rate today).

2 of my cloud mining purchases are making over 100% annual returns, which is amazing. But, we will see in a few months if they really end up making that much. There are huge risks with Bitcoin mining, like the cloud companies could go out of business, hash rates will decreases, and the price of bitcoin could go down. Even if I make 100% on my money in a year, if I then decide it is "safe" and want to invest a lot more, by then all the potential profits may be gone. Just because it does well this year does not mean it will do well next year.

All I can say is I am pleasantly surprised so far by the results from cloud mining.
