I haven't had a Dell in awhile, 4+ years, but I have to say, the Macs that I've had felt just as sturdy as the day I bought it. My personal MBP I got is from early 2017, and my new MBP I got for work less than a year ago feel exactly the same, besides one having stickers I wouldn't be able to tell the difference.

Every dell I've had starts creaking at the hinges after just a few uses. Doesn't feel as sturdy, the $600 difference is worth the longevity and integrity of the macbook hardware alone.
