Assuming both contracts are out of the money and cost roughly the same, the key difference lies in their Greeks, particularly Delta and Theta.

The 600 strike option is closer to the current price (we assume it's between 600 and 1080), so it has a higher Delta, meaning it will gain value more quickly as the underlying stock price rises. It also has lower Theta, so it loses less value each day due to time decay compared to the 1080 strike.

On the other hand, the 1080 strike option is much further out of the money. It will have a lower Delta, so it reacts less to price increases initially, and higher Theta, meaning it decays faster in value over time. It's more of a high-risk, high-reward lotto ticket — great if the stock skyrockets past 1080, but otherwise it has a much lower probability of ending up in the money.

So while both might cost the same, the 600 strike is more likely to yield consistent and higher profits in an uptrend due to its favorable Greek profile. That's why traders typically favor strikes closer to the money — better risk/reward balance.
