As mentioned, they are both great, and both very expensive for your 're-entry.'
And if you think they're not fast, you're in for a surprise!
IMO you will be -very slightly- more comfortable on the BMW, but I don't know if it's $4000 more comfortable.
The BMW will probably hold its value a tiny bit better, but no one knows yet.
The BMW is a hip bike right now and you're not going to get a deal anywhere.
The Monster is . . . a Monster. Great bike but known and not the new cool thing like the BMW is right now.
Just go ride one! Go ride something that's a few years old, too, to save that depreciation hit. Go Ride a Bonneville or a Thruxton too.
They come in different colors too if you don't like red.
