I upgraded from the Note 8.
To me the 10+ us not a huge upgrade, but I knew that before I bought it.
I do not have to have the latest tech toy, but my Note 8 had a dead spot that seemed to be getting larger, and it was chipped at the top of the screen.
The battery on the 10+ is better for sure, and I really like the wide angle camera. The pics when zoomed in were better on the Note 8. On the 10+ they look fake.
The faster storage is nice too.
The best thing for me is that size wise the 10+ feels much more like my note 2, which was big.
The only hesitation I had prior to buying the 10+ was the hole punch camera, but I hardly even notice it.
