[1.15.2] RegistryObject vs ObjectHolder

I currently store my items like below.

private static final DeferredRegister<Item> REGISTER = new DeferredRegister<>(ForgeRegistries.ITEMS, Mod.ID);
public static final RegistryObject<Item> MY_ITEM = register("my_item", new Item(new Item.Properties()));

private static RegistryObject<Item> register(String key, Item item) {
    return REGISTER.register(key, () -> item);
}

Can I use @ObjectHolder(Mod.ID) and make method register to return Item to store items as Item instead of RegistryObject<Item>?

Or is use of @ObjectHolder not encouraged?
