Difference between "stop" and "stop limit"

Hi! My question is: is there any specific case when it’s more convenient to set the sell of a stock only by using the “stop” function (instead of the “stop limit”)?
My understanding is that “stop limit” protect me from a sudden collapse of my stock value, because I can set a stop (which is the value I would like to sell my stock) and a limit (which is the minimum value I can accept for it). This “double protection” doesn’t happen by selling only with the “stop” instrument (where I set only the value I would like to sell my stock), so isn’t it more safe and convenient to sell using all the time the “stop limit” only?
Or, is there any particular case when it’s more convenient to sell only with a “stop”?
Thank you!
