Stop limit sell vs covered calls

Hi,

What am I missing?

I just started learning about covered calls and I am wondering If you are planning to sell 100-shares of a stock and you know your strike price, why not sell covered calls instead of stop limit sell? If you are assigned, you will get the premium on top of the total sell of the shares..

One gotcha is that one covered calls contract is 100-shares and covered calls are sold by contracts.

Thanks in advance
