Well, if you knew in advance that the stock will double, you would buy OTM options expiring in one year and bank few hundred percent gain. But this is hindsight. And this is exactly the issue: you know what is the best strategy only in hindsight.
If you knew that the markets will be moving sideways, you would trade only iron condors, wouldn't you? If you knew about 2008 crash in advance, you would buy puts, right? if you knew that NFLX will be up 18% after the last earnings, you would be OTM calls. But you don't. So you trade based on probabilities and your best knowledge.
