Corsair. I've never had any fail on my home computers, but have had several brand new kits fail when testing them on new workstations I have put together. I continue to only buy that brand since when you get a good kit, it runs virtually forever with no problem and if you get a bad one, exchange with corsair RMA is no hassle at all. Kingston is probably good but the brand name screams 'generic brand' to me. I used to buy loads of kingston cd-r's, they were always cheap CMC magnetics.
