Upgrading my iPad Pro 2016 to the Latest Pro 11

Hey all
What will I get if I buy the latest iPad Pro 11? I currently own the Pro 2016. I use my iPad for reading, basic writing and editting, media watching. So it is not something really advanced. My iPad Pro 2016 uses 4.2 Bluetooth chip while the Pro 11 2020 uses 5.0, will my braille display benefit from this as I feel there is a lag when I navigate text? Will the slight lag I experience with my bluetooth headphones improve with the 5.0 chip on the Pro 11?
Thanks a lot for any help
