I'm in the USA.
I suppose the difference in handling is that other vendors often have a wide open parts chain, and Apple doesn't. You can't buy them as a consumer or user, and as an APSP or AASP you can only get parts when ASD2 says there is a reason to, and you can only order them via GSX. In some cases, for example when it's a big item like a screen assembly or a mainboard, you have to send the item in first. All of that stuff takes time, and for many users, that is a reason to get next-day AppleCare support so you don't have that problem. You just get a replacement sent or someone at your door. Yes, that exists, just like with Dell and HP.
The AASP I contacted could not return the hardware until the repair was done, so bringing it in when the parts arrived was impossible. The Apple stores need 1 week for repairs nowadays.

Only for enterprise users, and it sets you back 400 EUR/yr. Dell charges 190 EUR for 3 years (in total). Quite a difference.
That kind of depends on the country you are in, I guess. Here in the Netherlands you first need to make an appointment (~1 week), then they order the parts (~2-3 days), then they fix the issue (~1 week). All in all you are without your laptop for 1,5 weeks. That is really lousy support compared to something like Dell's next business day on-site support.
