Stay away from Acer. I've seen too many of them come across my repair bench over the years. They're built to meet price points, at the expense of good engineering. Also not a fan of HP consumer laptops.
The office I work at now used to be all Dell, and yes, Dell has very nice on-site support if you pay for it. The repair techs were very nice and knowledgeable, BUT, I was constantly seeing them. One Dell Latitude went through 4x motherboards, 5x power supplies, 1x case, and it sat on the guy's desk all day long, never leaving the office. Went Lenovo (IBM) Thinkpads and never looked back.
Re: the Lenovo Yoga UA Fan linked to, we do have a Yoga 910 in the office that Lenovo gave us at a substantial discount, and it's been a good laptop, but is nowhere near as rugged as a Thinkpad. Costco has a Thinkpad X1 for a little more $:
