You didn't ask specifically, but I can tell you some of the reasons I like the Tesla console better.
I'm not planning on using the cup holders, so I'll have all that extra space in the Tesla console. I don't like the fact that the Evannex console has the gaping cup holder right in the middle of it, especially since I wouldn't be using it. I like that when the Tesla unit is closed, it is very unobtrusive. I like that the phone placement seems convenient, even if I may have to jump through some hoops in order to enable my wife to dock her iPhone 6 while it remains in its case. And perhaps most importantly, aesthetically I think it just looks better. But of course that's particularly subjective.
