What more efficient variables in a table or variables by itself?

I was wondering what will be more efficient variables in a table or by itself and why?

game.Players.PlayerAdded:connect(function(Player)
		Player.CharacterAdded:connect(function(Character)
---------------------------------------------------------
			function MakeDisplayArms()
			Vairbles = {
				CurrentCamera = game.Workspace.CurrentCamera,
				LeftArm = Character["Left Arm"],
				RightArm = Character["Right Arm"]
						}
				print(Vairbles[1])
				--To be done
			end
			MakeDisplayArms()
		end)
end)

or

game.Players.PlayerAdded:connect(function(Player)
		Player.CharacterAdded:connect(function(Character)
---------------------------------------------------------
			function MakeDisplayArms()
				CurrentCamera = game.Workspace.CurrentCamera
				LeftArm = Character["Left Arm"]
				RightArm = Character["Right Arm"]
---------------------------------------------------------
				
			end
			MakeDisplayArms()
		end)
end)
