Still have my Note 10+ and it's sad after 4 years they still haven't changed their design much; they removed the SD Card slot (even though there are dual sim models available, which means they have the space to add it back in), kept the screen at 6.8" but with 120hz support, same 12GB of memory, finally brought back 45W charging but it was in the Note 10+ before, better cameras but I'm not a professional so I don't care about that.
No reason at all to upgrade if your device works, Samsung hasn't innovated since the Note 8 and has only gimped their products instead of really going after Apple with a real enthusiast/professional device.
