I have had a few adventure style bikes and even though I havent got a strom at this time there a hard bike to replace ..they don't excell at one thing but do everything reasonably well.
I had a r 1200 gsa ................what a contraption ,couldn't get on with it ......and when it wouldn't start coming off the boat at Santander that was the end of that.
The BMW 800gs are pretty good, very light , excellent fuel mileage, great handling......not as comfy as a strom but a good contender, I have one and have enjoyed it ,but its for sale ......a new house forcing that otherwise would of kept it .
I have a KTM 990 r version aswell, a must say a havent owned a bike that makes you smile as much ....very plush WP suspension, good handling , mega power and torque, but it just wants to go wild all the time, the strom is a better touring bike.
I have seen that multistrada thing, I can imagine its a good bit of kit Mega power , brakes and handling no dought, but £14 k gulp and am sure it will have all the Italian trickyness and high maintanence, not like a jap ...jump on and ride it, wouldn't mind a ride on one all the same.
It may be a case of the grass seems greener on the other side.....but its not , I have been there, and when I get over the costs of moving house and new mortgage ect. a will probably have another Strom.................as a second bike coz that Ktms just "wheelie fun" .
