Having done a very similiar journey for 6 months last year, from a small village in Fribourg to Basel, I would have to say that I would not recommend it to my worst enemy. Even without traffic the journey is tiring and the amount of tunnels en route just adds to the tiredness. On top of that, all the Swiss people I worked with could not fathom out why I would voluntarily do such a commute and the daily comments of "you must be tired", "how long did it take this morning" etc. made me feel even worse
Add to that the inability to put ones foot down due to the sheer volume of speed camera's along the way means that I will NEVER go through that again.
