Which laptop brand do you like best? So which of them can you use the longest without problems and? So the most reliable brand?
Asus, lenovo, alienware
I like Asus.
I once had Dell and Lenovo, neither of which lasted long.
Were not overheated, fans not full of dust, as that is the most common "cause of death".
Now I have Asus, so far I'm satisfied…
MacBook from Apple with M1 processor
Apple is very good at the high-quality workmanship of their devices (others like HP too, of course, but that is also due to the price of the different models) and they can also score with their operating system, because it is adapted to your hardware and you already are very long in the PC / laptop game. Longevity is therefore also the order of the day, because you have good hardware and it will last for many years, of course the performance decreases again and again, from year to year, but I think, especially with your M1 chip and its successors, they will be even more durable. With Apple devices there have of course been problems (keyword front camera and butterfly keyboard), but there have never been many and there can be problems with all devices, regardless of brand.
Of course, ultrabooks from HP and Microsoft (Surface devices) are good devices, especially if you like Windows or even really need it (due to software that is unfortunately not available on MacOS), so you can also use these brands.
I would say that the brand doesn't exist, but Apple, Microsoft Surface and HP can be recommended. And what's also good is the DELL XPS.
