Advice - Cannondale SuperSix EVO vs Canyon Ultimate CF SL

I am looking to buy a new road bike after damaging the frame of my 10y/o old Felt. I am looking at two options which both are priced at about AUD $5k:

Cannondale SuperSix Carbon Disc Ultegra (mechanical), lifetime frame warranty, purchased from a LBS.
Canyon Ultimate CF S Disc 8.0 Di2 Ultegra, 2yr warranty/6yr guarantee, online from Canyon.

Just wondering if any readers have ridden both bikes or extensively ridden one and can give some feedback/advice. I will be test riding the Cannondale but due to living in a rural part of Australia, I don’t know anyone locally with a Canyon. The Di2 for the same price is very tempting but am a little apprehensive buying a bike online from Europe in the event of issues down the track.

Any advice will be much appreciated.

I bought an Ultimate CF SL with Di2 three years ago, and I love it. Very stable, very comfortable, and no issues at all with it so far. I can’t offer any comparison to the EVO, but I’ve been extremely happy with my Canyon. The only thing I wasn’t crazy about were the wheels, so I upgraded to a set from FLO.
