If you're pretty confident that you can select the right size, I'd go with the DB. I've fondled one of their Podium frames and they're very nice and hydro 105 is great (my Haanjo came with mech 105 and I swapped it out for hydro when I found a good deal on an upgrade kit).
Also, the 2017 model, with 6800 Ultegra, is only 150 bucks more. Totally worth it, IMO.
Edit: uh oh - just noticed that the Century 6C Carbon has 8000-level Ultegra for just under $1900. That would be very tempting. But the frame isn't red, so it's not as fast. Tough choice.
