The most surprising example I found was Dell Alienware support. Not sure if it's different from Dell consumer support, but I'd guess so.
Had to RMA an ultra widescreen monitor I use for work, and the experience was as smooth as silk and always in the hands of actual humans, who would follow up and push things forward.
Dell has always had good support, especially for business. I once bought a laptop second-hand that still had a few months of their highest support plan on it. Needed a screen first because of a few dead pixels. They had a tech come out to me at work and repair it on-site. A month before the warranty ended, the motherboard died. Same thing, replaced on-site. In both cases they offered to either send me the parts and DIY repair instructions or just send someone to do it. This was on a laptop I paid like $300 for (probably $2-3k new back then, it was a nice Latitude).
I’ve had their enterprise support on the phone with me for a dozen hours over the course of a week trying to get this SAN working. Their support remoted into it and had me manipulating physical stuff when required. They eventually got it going through a combination of hard resetting everything and updating firmware on half a dozen components + some software updates.
Dell doesn’t always have the greatest hardware, but their support really doesn’t rest until you’re satisfied. “No one ever got fired for buying Dell”.
