.. The 'Extended Technical Support' is not enhanced from their normal support, but instead of the standard 90 days you get 2 years (or longer if you keep paying). You are not paying for any other type of 'enhanced' customer service.
If you break your iPad, iPhone or Apple watch.. Apple Care+ kicks in and will be worth it.
If you are looking for help/support... your best choice will always be one of the great apple forums/sites.
