What Make You Like Gps Tom Tom More Than Garmin?

What make you like GPS Tom Tom more than Garmin ?
Someone offer me a new GPS Tom-Tom 920T for $425, but i used to have Magellan maestro 4040 & Garmin Nuvi 300.
I dont have any experience with Tom Tom.
Please tell me, what’s the good side beside these :
Bleutooth, MP3 player, FM transmitter, text to speech, 4.3″ LCD.
Thanks
