Sprint just offered me an upgrade. I have used a Nexus 6 since 2015. I was wondering if anyone can comment if the Samsung S8 is an upgrade?

I can get it for $399 new at Bestbuy. When I did a comparison the hardware was not that different.

I was also considering the LG G8 ThinQ for $17.50 a month lease. Is this phone a big upgrade from Nexus 6?

Any advice appreciated.
