Thinking about buying a used MacBook (2018 or 2019)

Hi everyone so I want a bit of insight, so I am already the owner of a 2015 Imac which is still pretty good even though it has an HDD. I need a new laptop due to my current one being really trashy( HP) . I have the choice between the MacBook Neo or a Used Intel MacBook. I asked to some people who directly told me to get the Neo but honestly even it seem powerful I just need something that can do basic schoolwork. Therefore is the 2019 16inch MacBook Pro a good ideal , and what about the 2018 15inch 2018 model

Thanks for reading !
