US Basement Rec Room for sports and games - 75" QM8K or 85" QN90D

Hello - first time buyer of a large scale TV and seems like I've read reviews on each of these TV's that also point to the other one as being better lol. This will be in a basement room that is mostly dark so i'm not worried about performance in bright settings.

Both of these are currently around $1800-$1900 USD

QM seems to be better at gaming maybe, but not as good at sports?

QN seems to be better at sports maybe, but not as good at gaming?

Bravia 7 75" is a few hundred more than either of these and doesn't seem to review as well as the other two, but real world folks keep saying this is a great TV.

Any real world advise experience with any of these would be of great help!
