Well, let me start off by saying asking a yamaha owner about which is better between yamaha and suzuki I kinda think you'll be getting a bias opinion.
I own a yamaha R6, 2006 model and I absolutely love it!! I've had it since Feb last year and have had nothing but joy from it. To use a familiar phrase, "It does exactly what it says on the tin" By far yamaha are better with build quality, reliability etc. And the R6 set the bench mark for all other supersports 600's on the market. Then they did the same all over again with the new R6. In 2006 the R6 beat suzuki and every other brand to win MCN's 'MACHINE OF THE YEAR' award AND 'BEST SUPERSPORTS 600'
Hope this helps you a little. But I will say, as you're a newbie. Go on sit on all the bikes you're thinking of getting. If they feel any way negative when you're sitting on it in a showroom, this will multiply by 10 when you get it out on the road.
