I have owned both --- still do
My biggest problem coming from the V Twin world to the F6B is that on the F6B 85mph feels like 50 and for about the first year I was certain a ticket was in my future.
My best description is that it is the closest thing to an electric motorcycle feel. The throttle/torque curve is the most linear machine I have ever driven--car or bike. It starts off pulling strong and does not give up! It looks big and bulky, but that is just the looks. It does not handle that way at all---acceleration and braking are world class--never had a Harley that could touch it. The VRod was close--very close. The bike is stealth like--very very quiet.
I have owned Harley and Victory and both are fine machines. My Harleys include Ultra Classic, Heritage, Fatboy, Road King, VRod and Sporster. I currently have an 06 Street Bob. In all of my HDs I never had the service issues I hear people talk about. The exception is the early McNelli Moretti EFI---I did replace a stator while on a weekend tour. There is the 5K service with HD that costs about $350 for a 5,000 mile ride. The Honda has a ton of Honda auto DNA which makes it about as close as maintenance free as any bike out there.
