If you're tallish you probably won't like the CB1100, it's tiny. I'm 187cm tall, the seat height is around 775 mm from memory and when I sat on one, what with the foot peg position it felt too cramped. The small tank (14.5L) is way too small as well, I didn't even bother taking it for a ride.
Now the Versys 1000, that's a different story. I rode a demo bike for around 120k's, probably the most comfortable bike I've ever ridden and that includes Goldwings, ST1300s, FJR1300s etc. The riding position was just so right for me, the seat so comfortable. The screen was hopeless (lots of turbulence whatever the position) but that's easily fixed.
