I used to repair Dell consumer equipment at my job, and Dell Complete Care was hands down the best warranty out there.

Dell Enterprise support is still highly variable, depending on the tech you land with. I've had to involve my sales contacts several times when techs wanted to do absolutely crazy things to hardware that was obviously dead.

You can self-certify and manage your own component replacements, which works from small to mid scale. We do this for about 1,000 servers and it works pretty well; no phone calls where you roll the dice for quality of the tech, and I like frobbing hardware from time to time, it's a nice change from hacking C++ or PHP . . .
