Well one of the main reasons of buying a Mac is for the stability. I sincerely apologise in advance for the wealth of ******** I'll be spewing below. There's no question that you can get OS X on non-Apple/official Apple hardware, but why do it? Pros and cons (IMHO) below.
Apple Mac:
Hardware
Apple's hardware is as it is for a reason. On Apple notebooks (and desktops), you get the multitouch gestures which are simply unrivalled by other OEMs. The build quality across the Mac line is really impressive. There's a lot of hate for 'smaller and lighter', but if you're somebody who appreciates technology, you'll really be amazed with what they can pack into a Mac.
Really good materials are used. Aluminium, glass, backlit keyboard on all notebooks -- really gives you a feeling of quality and durability. Plus Apple is moving to near-exclusivity with PCIe Flash storage, so you'll be getting 800MB/s speeds on the SSD consumer products alone.
Other advantages are great battery life with the notebooks. Yeah, PC people laugh about how Macs don't have removable batteries. Except, they did up until around 2009. If you see Apple's evolution with the notebook lines, you'll see how the batteries got bigger and bigger to increase from a 5 hour battery life to a 12 hour battery life. Look inside a MBA/rMBP. The battery is a good 60% of what you see.
And of course, standardised hardware means no cocking about with changing parts and testing this and that if something goes wrong. Which brings me to ...
Support
Apple's support is arguably the best in the industry, rivalled only by DELL/HP's business support. Anything goes wrong? Apple Store, or get on the phone to them. It's a different mentality to PCs because consumers may get the feeling that everything's 'dumbed down', as you let somebody else do the work rather than getting your hands dirty.
Hipsterism
You'll get a lot of glaring looks when your Apple logo blinds passers-by. But if you're the sort of person who likes to smell their own farts, get a Mac for this reason.
Summary
I maintain that people who use computers for work -- where they make their living exclusively off computers -- will almost always pick a Mac. They want something that works, and if it goes wrong, have swift support to fix it. They don't want to cock around with eeking a few more FPSs from their games. They just want to work.
Hackintosh:
Hardware
It's your own hardware. Cheaper, no doubt, and certainly can be more powerful than the limited range which Apple offer.
However you've got the issue of getting the thing to work in the first place, in addition to having to buy certain types of hardware (if you want to make OS X run natively, rather than on an AMD CPU or something like that).
I knew a bloke who got OS X (native!) running on his Alienware laptop. Everything worked except the wifi. The experience wasn't nearly as good in my opinion, but if your main concerns getting the best hardware on OS X for the lowest price, a Hackintosh is for you.
Support
You are the support. It's definitely great if you enjoy building your own PCs and troubleshooting problems. I used to love this stuff too, then I got old, boring and just wanted something that worked without me having to cock around with it. Again, depends on your mentality.
Hipsterism
"I run OS X, but on non-Apple hardware. I stole a free operating system."
Nothing more hipster than that.
Summary
It's all down to what you enjoy. A simple update to OS X can brick a Hackintosh. But then you have the satisfaction of making something seriously powerful for a much lower price. If stability & third-party support is your main concern, then shell the extra out for a Mac.
TL;DR: neither is better, it depends on what you need from OS X and what you want to use a computer for. Pick whichever you feel is closest to your heart, and best of luck whichever you use.
