Laravel Resources Vs Custom Controller Functions

I have BIG doubt . Hope someone help to clarify this .

I m really worry about the best practices of laravel 8 . Always I m trying to build up my application using laravel "resources". So Its very useful me to build up CRUD application .

Is that necessary or best practice to build up application using resource in controllers or Do i need to follow up my own custom functions in controller class

Please note : this is not Web Service. This is CRUD based Application.

Eg:

Custom Controller Functions and Routes

Route::group(['middleware' => ['auth']], function () {

    Route::get('subcat/loadall', [SubCategoryController::class, 'loadDataTableData']);
    Route::get('subcat/index', [SubCategoryController::class, 'index']);
    Route::post('subcat/create', [SubCategoryController::class, 'create']);
    Route::post('subcat/edit', [SubCategoryController::class, 'edit']);
    Route::post('subcat/update', [SubCategoryController::class, 'update']);
    Route::post('subcat/save', [SubCategoryController::class, 'save']);
    Route::post('subcat/delete', [SubCategoryController::class, 'delete']);

});

Resources Controller Function

Route::resource('maincat', MainCategoryController::class);
