$3k for a road bike you arent racing.
As mentioned, perhaps expand your options and look at other brands?

Given your arent competitive, an $1800 105 road bike that fits you well will be 97% of a $3000 road bile that fits you well.

Your cash though.

I bought a Praxis Zayante crank for an upcoming build because i loathe the 4arm Shimano cranks. The Zayante crankset is something like 80g heavier than an Ultegra, if i remember correctly.
Thats minimal to me.

Lower bike price allows for swapping what you want when you want.

I would focus on stock gearing. I want a bike with a GS rear derailleur so i wouldnt buy something with an SS rear derailleur as i would need to change the RD, cassette, and chain.

I doubt the stock wheels on either bike are as grest as the known parts, which is why buyibg lower could be good since you can upgrade the wheels.
