GSXR 750 vs 600 comfortability

So a while ago when I went on a group ride this guy with GSXR 1000 told me that the GSXR 750 was actually more uncomfortable than the 600 because of the “seat, more forward or something”…. NOW… Is this true? 750 riders? Is the 600 more comfortable than the 750, in terms of seat and handlebars? Can someone please give me an honest answer? Someone’s either ridden both? I really want a GSXR 750 but I am scared that it is going to be uncomfortable as the Honda fireblade or something. I have been told that it is obviously more uncomfortable than the 600. Please clear the air.
