That's just like, your opinion, man.

More eloquently, I prefer the regular version. I prefer having all the interface already presented to me rather than hidden away. The one thing you could say is that the mobile version restricts itself to a narrower width automatically, but it's pretty trivial to write custom CSS to do the same for the regular version, or just resize your window. People still know about "move tab to new window" and how to resize their windows, right?
