Referencing Weapons Clientside

[devilsknite1]

So I know from experience that referencing weapons clientside can be done in multiple ways, the easiest two probably being the following.

Method 1:
Weapon NPC Foo

PHP Code:

//#CLIENTSIDE
function onCreated() {
  ( @ "Bar" ).foobar();
} 


Weapon NPC Bar

PHP Code:

//#CLIENTSIDE
public function foobar() {
  // code
} 


Method 2:
Weapon NPC Foo

PHP Code:

//#CLIENTSIDE
function onCreated() {
  findWeapon( "Bar" ).foobar();
} 


Weapon NPC Bar

PHP Code:

//#CLIENTSIDE
public function foobar() {
  // code
} 


Which way is the "correct" way of referencing another object clientside? What are the differences between the two, if any? In the past I have always used method 1, but now I find myself most certainly wanting to use method 2 as it is an actual command loading an object (findweapon/findweaponnpc) rather than simply listing another weapon name. Might there be more functionality advantages to method 2 versus method 1 or vice versa that I might be missing?
