To be honest, I don't think anyone really knows the answer to your question and I suspect all you're going to get is people's personal brand preference. For example, I've been buying G.Skill for a while now because every time I've gone to put a rig together they were about the cheapest for the product I was looking for, offer lifetime warranty, and I've never had an issue with them... so they get my business again. No doubt others will have had similar experience with other brands and bad luck with G.Skill.
Here's Puget systems post from last year: https://www.pugetsystems.com/labs/articles/Most-Reliable-Hardware-of-2014-616/
They apparently like Kingston and Crucial, as they've had pretty close to 0 failures. But I have no idea how reputable that post is, or whether other brands are necessarily worse.
Bottom line is (IMHO), get the product you want at the best price you can. You'll be very unlucky to get a dud.
