I have a lenovo laptop (I never even heard of it until I bought it and now I’ve seen it advertised online). One of my siblings has two dell laptops, one works very well (pretty new) and the other is not too good (older, but I dont think it was too good from the beginning). The only difference I have seen in mine (lenovo) is a bit more in price and it holds less memory than most of the dell I see advertised. Other than that, I am B”H very, very happy with it. IMO, it works as well if not better than the dell desktop I usually use.
OP, I would recommend checking user reviews on cnet.com before making any final decisions. Good Luck!
