I’m a power user so I’d go for the 8 gigs. But it doesn’t make a difference. Android does not use 8 gigs for anything. Of you are using alot of apps at the same time then yeah it’s nice but the 6 gigs can handle that as well ( not even games will past 6 gigs.)
No matter how much ram a device has android operates with what it’s programmed to do. So if it closes apps at when ram is past 5 gigs it will do the same with 8 gigs even though it has the ram to do more.
So to me personally the six gigs doesn’t do anything more than the eight gigs.
That being said if the device has a couple years of updates I’d go with the 8 gigs incase android gets more demanding.
Hope this helps.
Based on what u siad i dont really qualify ( always end up selling my iphones.) For me its the sheer amount of features you get. They may not always be as polished as the apple counterpart but i love being able to customize my phone to the point of it being “my phone.” Compared to picking up any apple device and its the same song and dance.
