Which reputation? I used to work for a dell heavy hoster with thousands of dell servers almost 20 years ago - and apart from them being cheap I have nothing good to say about them. Worst is the remote management - several generations of DRACs all broken in new and interesting ways, and support is useless. You just get better discounts at that scale, which for a business owner drowns out the complaints of the tech people.
Notebooks also have similar bugs over generations - and nowadays they also feel even cheaper than they used to be.
Displays were somewhat acceptable - given you're fine to work around the DPMS bugs they have in pretty much every display for the last two decades - but their display selection page is unusable and lacks most interesting details. So it is better to just get something you can check out in a shop.
Note that those are deepseek, not chatgpt. I've largely given up on chatgpt a long time ago as it has severe limitations on what you can ask it without fighting its filters. You can make it go on hallucinated rants just as easily - I just nowadays do that on locally hostable models.
