there really is no comparison. the fz-07 is awesome. they gave me my old 500 as a loaner when i had my first service and it felt like i was riding a power wheels toy. the fz-07 has monster torque. first gear, if you give it too much gas, your front wheel is up off the ground. i have owned a ninja 900, shadow 1100, vtx1300, cb500f. this is by far the best and most fun bike i have ever owned, hands down.
if you can find a 2015 fz-07 they have a rebate. i got mine for 6100 before ttl, a friend of mine got his for 5700 before ttl.
