I've had mostly good experiences with dell's XPS 13 laptops. Coil whine has been a problem.

Dell is the only company I know of that really stands behind their products. The default(at least here) warranty includes next business day on-site repair.

The times I've had issues during the last 15+ years Dell has sent someone to fix it, fast. Nobody else seems to be willing to do that if their product fails. Must be really expensive for Dell when something goes wrong.

They do however stop producing/selling batteries much earlier than they should...
