Samsung QN90F
As Samsung's top-performing 4K Mini-LED TV, the QN90F delivers a bright, colorful picture hold ups up better in brightly lit rooms than the S90F. It's stuffed with nearly every streaming- and gaming-related feature you could ask for outside of Dolby Vision.
Pros
- Incredible bright room performance
- Great color accuracy
- Tons of gaming features
Cons
- Middling audio
- No Dolby Vision
- Minor Tizen OS issues
- No ATSC 3.0
Samsung S90F
The S90F doesn't get as bright as the QN90F, but its OLED-driven picture is slightly better on account of its pixel-level contrast control. It offers almost all of the same features as the QN90F, but it's similarly missing Dolby Vision support.
Pros
- Incredible color accuracy and color volume
- Tons of gaming features
- Exceptionally thin design
Cons
- Middling audio
- No Dolby Vision
- No ATSC 3.0
- Minor Tizen OS issues
