I liken them to the opposite sex.
I never rode a bike or a woman that i did not enjoy......even the bad ones were still alot of fun.
I have had more BMW than anything else and it makes no sense because the nearest dealer was two days and a 7 hour ferry ride away. There was never a K, F or an oilhead sold here until two years ago. We have a very good dealer now and i am grateful.
I own whatever works for me. Honda scooter around town. Klr for the winter duty. K bikes for day trips and the GSA for long dirty rides.
