yup - my GS has all the bells and whistles i need in a bike - and if I were to be truly honest about it, I also think she's way better looking than those big Pamela Anderson adventure rigs - with their huge, oversize tanks - all pushing up and out and all over the place.... goodness sakes.
Seriously though - if I were to be contemplating a two year, multi-continent ride - maybe the adventure would be bring a little more to the card table ..... but I use my bike mostly for commuting - day trips when I can - and the occasional weekend away ....
The GS is way more than enough bike for me ;-) and as Nyuscdjs just suggested - it's all about preference. I'd encourage anyone to move towards the bike that calls out to you.
