65 or 77? See room setup.

Here is my setup. Struggling with choosing between 65 or 77. Viewing distance is 12 ft. Tv can be wall mounted on either wall. Living is relatively small so concerned 77 is too big

I bought both a 65 c4 for 1300 (open box excellent) and a 77 c3 for $1499.

I generally like my current setup, I don’t want a tv that will dominate the space but also know bigger is usually better …. Thoughts…?
