Help!!! Need opinions and more!

I need some opinions on this bike please!! I’m new to cycling and need y’all’s help!
I can either get this bike which supposedly all brand new parts with unknown mileage on the frame, or for the same price I can get a brand new trek Domane Al 4 gen 4. Which yes I realize the trek is endurance this the supersix is a race bike. I love the Idea of a race bike more but I have a Feeling endurance will better suit me in the long run. What do you guys think is best?? Buying use even with new parts scares me. Am I better off buying new or is that deal just too good to pass up for the price? 1,600$ is the price.
