I've used many laptops and never had one last as little as three years old. I've had a few issues with graphics cards not lasting, one dual GPU laptop failed after a while and I had a little Dell XPS with the faulty batch of Nvidia cards. I have an eight year old gaming laptop which I still use regularly and also has no issues. I had a friend who was quite taken with a DV camcorder and wanted to see some of his capture, I couldn't find a charger for one of my recent Vaios so dug out a very old Vaio ultrabook (from 2004 I think, was the first consumer laptop with an LED backlit screen) and it powered up fine then captured the footage.
I think the difficulty with a laptop comparison site is there's many aspects beyond the simple specs that are important, you can have a machine with good specs on paper but if the screen quality is poor and the keyboard is rubbish then it's not worth considering. Also the computing market is in a mess at the moment as it deals with the fallout from ram and SSD prices going through the roof thanks to the genAI companies, it started with the raw ram and SSD prices but now it's really hitting the prebuilt market so prices are rocketing as well. I used to choose laptops on their repairability but even business laptops often are using mostly soldered parts and difficult t repair in the drive to make slim and light machines.
A final caveat is I'd recommend looking up the Intel or AMD sites when checking what they are exactly, I find some of the Intel naming misleading and bought what I thought was a higher rated processor but due to a change in naming it was actually a lower voltage and therefore lower performance one.
I normally use this site for checking laptops as they have a good amount of detail and they usually compare to a number of other machines too:
