AK vs AR has been a good debate for a while. While I see pros and cons to each option, if I was going to buy one today, I would consider ammo price and availability. The 7.69/39 is always available near me (South Texas), and is about 5 bucks for a box of 20. I can't answer from personal use of an AR, I do like my AK though. However, if you're an avid collector like me, you'll probably end up with both anyway, so then you can be the judge. I'd just like to find a good AR under $750, but that'll be on a different thread.
