I'm of the opinion Samsung only throws a ton of RAM into the phones because they manufacture them and want to win the spec war. More RAM is automatically better to consumers even though it's useless if you don't multitask enough to use it. I don't think you will notice a difference but I also don't know your usage habits.
Same with storage, I can't say if 128 is plenty for you or not. For me personally it's absolute overkill. I'm typing this from my Note 8 that I've used for nearly 2 1/2 years as my daily driver, only used 42.6Gb and have 21.4Gb free still.
I've got the photos and video I've taken with this phone on here and all my apps. I have a handful of games, social media apps, banking, photos editing apps, apps needed to control some cameras and drones.
