I'm on a 2013 Macbook Pro right now. I've had zero problems with it. It's fast, reliable, quality hardware with a battery that lasts me around 10 hours a day (if I use Safari, if I use Chrome it cuts the battery down to 7-8 hours...it's really a hog now).

BUT, I'm in the market for a new Laptop. I'm one of the few people that liked the announcements from Microsoft about Windows 10 and honestly, I'm bored with Mac right now. So I'm looking at good laptops that will exceed or at least meet the quality and battery longevity of the Macbook Pro. So I'm seriously looking at the new (not out yet, but announced) Thinkpad T250s. Great keyboard and unique Track-point mouse (always intrigued me), battery life near 20 hours (with the extra 6-cell battery option), durable build (like a tank), and the ability to dock it. Not to mention I could also throw Linux on it without any problems (Linux on this Macbook Pro is spotty at best, as some things work, some are wonky...same with Bootcamp and Windows).

But bottom line is, which platform you choose doesn't really matter much anymore. I could switch over to Windows from being 100% Apple for the past 8 years and not have much of a problem.
