Re: DeX vs normal Android
I'm still waiting for my Tab but researching it a bit, I came across this Samsung page which lists all the apps that work with DeX...I assume that this means that Samsung tested them for use in DeX. Perhaps sticking with these would provide a better experience.

For myself, I plan to play with DeX but I'm really buying the Tab S4 for the Android experience and have a Galaxy Book for when I need a desktop.
Re: DeX vs normal Android
I havent looked into Dex yet but I often use a bluetooth keyboard and mouse with my tablet
