I doubt that you could go wrong with either bike. Like you, I went back and forth and then chose the 650 Strom. It may be the best bike I've ever owned for commuting and touring. My off-road skills are so modest that I've never been able to max out the strom there but I now ride on Colorado back roads quite a bit with a fair amount of confidence.
