On average my macbooks, iphones, watches don't last a year. AC+ shortens and reduces the negotiation headaches.
I always try to go to Genius Bars and avoid AASP. The bars are generally much more benevolent in developed markets — US, HK, SG — compared to developing like Bangkok.
With careful and polite negotiation you can often get free repairs and replacements (and once in a blue moon, upgrades) out of warranty.
While mostly in Asia, I often start a support case with Apple Support US, they can make a favorable decision and transfer me to their global branches, who then can direct a local Bar or AASP.
The Genius Bars in Mainland China (I mostly dealt with the one in Shenzhen) were great.
