So the BMW rides better, accelerates better, goes faster, handles better, has more modern systems, and if you believe what is written competent systems integration. So the BMW must cost thousands more than the Harley..... 
That did make me chuckle.
Although riding my new K1600GT Sport this morning there are a few things I'll miss from the CVO Streetglide;
Harley's infotainment screen is way bigger than the BMW nav - although it has to be said; I had one replacement head unit on my first Streetglide in 12 months and had to be replaced on my 2nd' Streetglide in an 18 month period.
The 2 thumb joysticks on the HD are easier and more intuitive to use than the BMW controls
The speakers on the BM are pretty feeble - not in the same league as the system on the CVO Streetglide
Backlit switchgear - BMW doesn't have it
I'd grown to like the HD top opening panniers/bags - found them easier to live with on a day to day basis, easier for carrying a laptop bag, usable whilst on the bike (e.g. if the sun disappeared I could just pull over and drop my sunglasses in the bag). Having said that the GT panniers will easily hold my crash helmet which is useful when nipping into town and don't lose space to speakers / amp / wires.
And that's about it, just minor stuff - in every other respect the BM wins hands down and by a significant margin. Resale prices on used CVOs in the UK are not great, but thankfully I only had to find a couple of grand to move on from my 3 year old FLHXSE to a brand new fully loaded K16GT Sport.
