Fenix 7s vs 7 sapphire solar

I currently have the 7s sapphire solar and i love it, but im thinking that i may want to have the regular 7 size vs the s.  From what I am reading the only differences in the two are the size and battery life.  I havent heard of any negatives of either watch.

Has anyone upgraded from the 7s to 7 by chance and if you did, did you have any issues reselling the 7s?
