I think you are trying to compare a Sherman Tank with a Lamborghini.
Both my Stroms have been tough as nails, if I throw one down the road I fully expect to ride it home, I would expect my MT09 to require a trailer (it has twice)
The Yamaha is a absolute blast to ride and has not given me any mechanical issues but there is a reason the bike is so light, there is no meat in the metal.
My MT was knocked over while parked and one of the bolts holding the handlebar mounts to the top triple was bent (far to easy), my son dumped it in the wet, it slid a few feet and made a huge mess of the motor, even rubbed through the fuel tank, good protection is required.
The repair costs in parts alone was more than 50% of the purchase price.
If I just want to have fun I take the Yammy but if I want to go some place it is the Strom for me.
I think everybody should try the Yamaha, but if I could only have one bike there is no doubt it would be a Strom.

Live life on the edge you will see more that way.
Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
