sorry for taking so long to get back to you.
Car mode/ smart mode - seemed nice at first but not customizable enough for me, reinstalled car dock v3
As far as the desktop docks,
there are 4 choices I only remember 2 and only use one.
The desk clock is pretty much the same with a little more functionality. nice I kind of like it.
