Simple question about "count" command

[jwllorens 43]

{

  if (_x isPlayer) exitWith {true};

  false

} count _thisList;

 

is generally faster than...

 

if (({_x isPlayer} count _thisList) > 0) then [{true},{false}];

 

assuming 

a: A player unit is in _thisList;

b: The player unit in _thisList is not the last element in the array.

 

Is this correct to assume?

You can measure the performance yourself, no need to assume anything. However I doubt any of the given code will run.
