Quick note about the Dells: The Inspirons are their consumer line, which is often cheap junk. Nothing inherently wrong with them, but they’re a race to the bottom like any other consumer laptop. You’ll also hear about their failures because they’re just everywhere… a lot of college students, cheap businesses, home users, etc. will have them.
The Latitudes are their small biz machines, which is slightly less cheap junk supported by better support (especially if you pay for on-site support: the only way to guarantee a US-based tech addresses your issue, comes to your home with parts in hand, and talks to you like a real human). If you buy an Inspiron, you’re going to spend hours, days, and weeks troubleshooting anything with their outsourced tech support.
The XPS line is their prosumer line, which sells more premium features (better screens, gaming stuff, etc.) but not necessarily any more reliability, and importantly, not necessarily any better support.
Lenovo has a similar setup. Their ThinkPad business machines with premium support addons are the most supportable, especially the T series workstations (as opposed to the X series superlights). The Thinkbooks, Lenovos, Yogas, etc are their various consumer and prosumer brands. But if you want “shit actually gets fixed” support, you have to buy a ThinkPad with the on-site addon.
Asus also offers global on-site support, I think, but I think their customer service in general is just poor. It’s a Taiwanese cultural approach to things, where they try to make a good product upfront but after that it’s buyer-beware, and their after-sales service attitude isn’t the same as the American companies (like Dell) or even the Chinese ones like Lenovo (who inherited their service culture from IBM). They make great gaming products, but I wouldn’t count on them for any business-critical workstation.
(Edit: Ah, sorry, missed the part where the OP is not in the US. Hiding the rest of this as irrelevant.)

Another option is to find a local computer store (if they still exist). Microcenter is really good, has great products (both first and third party) and they have on-site support at their stores.
Best Buy has gotten a lot better in recent years. Not sure about GeekSquad, but if you buy their extended warranty (or sign up for a Best Buy Total membership), they will replace anything that doesn’t work.
Costco is another option that will give you a longer warranty.
But the end principle is the same: Laptops are race-to-the-bottom commodities. The small biz machines are a little better, but not enough to prevent failures altogether. If reliability is important, having local support and/or a replacement plan that can get you a working machine back in a few days is critical.
Or… just buy the cheapest laptop you can find, put away the money you save, and buy another one when it inevitably breaks. That way you not only fix the problem but get an upgrade in the process too…
