Garmin nuvi 3597LMT or TomTom Go 6000?? HELP!!

[riki66]

I just bought a car (my first car actually) and i was going to buy a new gps for it.
My car is a lancia ypsilon with blue&me software and i want my gps to have bluetooth speaker functionality.
I also want "voice-activated navigation" and lifetime traffic.
After researching online i found myself torn between the Garmin nuvi 3597LMT and the TomTom Go 6000.
I must say that i always used this forum to download and install garmin map on some garmin unit belonging to a friend of mine and that
i am pretty accustomed with garmin units now (on the contrary i read that tomtom units needs to be "hacked" before installing downloaded map and it's not very easy to do for the new models such as the go 6000).
At the end i decided to ask here where i always found the answer to all my problems with garmin maps.
So i'd like to know by comparison which one is the best gps unit between those two. (considering the functions stated above and also that i'd like a "state of the art" navigator)

EDIT: I forgot to add that budget is not a problem so suggestions for different unit than the one posted (more expensive or less) are more than wlecome.
I also have one last question: When does garmin "releases" the 2014 gps unit??' I just wanted to know because if they relase them by january i might wait and go with the new one.
I also hope i have posted this in the right sub-forum because i couldn't find one with dicussions on different navigators.

Sorry for my bad english
