Depends on the specs but the main thing that I have seen that kills laptops is dust as people don't clean out the fans and insides. So when you have enough dust buildup, the laptop heats up which causes the components to throttle down. Also depends whether or not it has a SSD or Hard Drive as laptop hard drives are typically slow and gets even slower as time goes on. Usually if you replace the hard drive with a good SSD, you will see a night and day difference.
The good news about buying a laptop this year as opposed to previous years is that you can get pretty nutty specs without breaking the bank thanks to Ryzen 6-8 cores being very affordable.
I usually go with Asus and Dell but I'd always check the reviews as every company has good and bad models.
