Both good bikes with the Versys being the sportier of the two. Back in '09 I went through the same debate with myself. I opted for the Strom for practical reasons, a large back seat/luggage rack for carrying gear, at the time a larger gas tank and centerstand capable, front and rear fenders that made an attempt to keep you dry, and roomier ergos. The Strom seemed like the better long distance bike at the time, it all depends on your priorities.
I always tell people to get a test ride. I can't tell you how many bikes I've ridden that on paper I was sure would be great, but ended up hating once on the road. The FJ09 being one, a fun bike but the buzzy vibration at 4k RPM was a deal breaker for me.
