If (positive){} else return; vs if(negative) return;

Hey guys, so I’m a bit confused with this matter.

So which method actually performs better and is more secure? And why are both used in common in a file written by the same person?

// METHOD 1

bool SomeFunction()
{
if (Positive)
{
// do stuff
return true;
}
else return false;
}

// METHOD 2
bool SomeFunction()
{
if (Negative) return false;

// do stuff
return true;
}

It is more a question of what you need to write clearly and quickly and not a performance/standard coding/secure thing.
Although, you do not need the “else” word in the Method 1.
