Mouse click to select and Isolate

Hi- I need some help determining the right way to isolate an object after its selected. So far I have been able to set tags for each gameobject, and I have a selection created that reads the part selected once its clicked with the left mouse bottom as you can see below.

Looking for online answers, I noticed that one way is to enable/disable the other gameobjects once one is selected. The other way I saw was to hide/unhide. Can someone tell me whats the best way to accomplish this. Thanks

using System.Collections;

public class Selection : MonoBehaviour {
Ray ray;
RaycastHit hit;

 void Start () {
 }

 void Update () {
     selection();
 }
 
 void selection () {
     // Use Input.GetKeyDown() for single clicks     
     if(Input.GetKeyDown(KeyCode.Mouse0) )      
     {        
         // Reset ray with new mouse position25.    
         ray = Camera.main.ScreenPointToRay(Input.mousePosition);  
         if(Physics.Raycast(ray, out hit)) {  
             //hit.transform.tag used to refer to especific object tag name
             if(hit.transform.tag == "Leftdoor") {      
                              
             } 
             if(hit.transform.tag == "Rightdoor") {             
                         
             }              
             if(hit.transform.tag == "Trunkdoor") {               
                                 
             }             
             if(hit.transform.tag == "hood") {     
                             
             }                
             if (hit.transform.tag == "Untagged") {      
                          
             }             
             Debug.Log("You have selected: " + hit.transform.tag);           
         }      
     }      
       
 }
