Which of this 2 codes it's the best for get any key

Option A: Getting each key one by one.

Code (CSharp):

1. [System.Serializable]
2. struct EventFirer
3. {
4.  
5.     [SerializeField] UnityEvent uevent;
6.     [SerializeField] KeyCode key;
7.  
8.     public void Invoke()
9.     {
10.         if (Input.GetKey(key)) uevent.Invoke();
11.     }
12. }
13.  
14.  
15. class EventController : MonoBehaviour
16. {
17.     [SerializeField] EventFirer[] firers;
18.  
19.     private void Update()
20.     {
21.         foreach (EventFirer firer in firers) firer.Invoke();
22.     }  
23. }

Option B: Getting the key from Event

Code (CSharp):

1. [System.Serializable]
2. struct EventFirer
3. {
4.  
5.     [SerializeField] UnityEvent uevent;
6.     [SerializeField] KeyCode key;
7.  
8.     public void Invoke(KeyCode current)
9.     {
10.         if (current == key) uevent.Invoke();
11.     }
12. }
13.  
14.  
15. public class EventController : MonoBehaviour
16. {
17.     [SerializeField] EventFirer[] firers;
18.  
19.     void Update()
20.     {
21.         if (Event.current.isKey)
22.         {
23.             foreach (EventFirer firer in firers) firer.Invoke(Event.current.keyCode);
24.         }
25.     }
26. }

Any other idea? How you use to do it?
