Need help identifying a bike + comparing 2 bikes

Hey everyone,

My main intention behind this post is 2 things:

1 – Getting some help in identifying a bike.

2 – Help in deciding between 2 bikes

The bike to identify is the Pinarello GAN T600 with Shimano 105 which the seller has stated is 2018. I've tried reverse image searching this bike and scouring the internet and could not find this exact match. If anyone knows this or has any further insight on it, I would greatly appreciated it <3

The bike I am comparing this to is the Merida Scultura 4000 which also has the shimano 105 and is a 2020 model.

Both bikes are in great condition with the Pinarello negotiated down to $1300 AUD (897 USD or 776 EURO) and the Merida down to $1500 AUD (1035 USD or 895 euro).

Assuming bikes fit great and are both in good condition, which bike would be better?

Thanks 🙂
