November 2023? Are you talking about Pixel 4a?
Either way, people on this forum and mods always make the same argument, which I think is a very good one: spending more on a newer version, especially Pixel 6 or later (guaranteed 5 years after release date), means you get more use for your money since they're guaranteed to be updated for longer. More bang for your buck as they say.
But if you were to get the 4/4a, it'll work past the end of life date, it just won't get any operating system updates, which is not safe from a security standpoint and renders it obsolete.
