Why are you basing your choice on reports of, alleged, bad customer service?
I've used Dell PCs and laptops for more than a dozen years and, in all that time, found them to be sturdy, reliable, well-built machines.
I've never had occasion to use their Customer Service team.
On the two occasions that I needed to claim on their accidental damage warranty (think student + laptop = bad mix!) a quick 'phone call to Dell and an engineer was with me (at a location specified by me) within 24 hours.
