The Samsung QN90A and QN90B are similarly priced and both offer excellent picture quality. If you prioritize newer models and slightly better performance for mixed usage like viewing in both bright and dark rooms, watching movies, sports, and gaming, the QN90B would be a suitable choice. It has an advantage in upscaling and as a monitor usage over the QN90A. They both have great speaker systems and support various HDR formats except for Dolby Vision. If your main concern is value and you're looking for performance that is nearly identical, the older QN90A could suffice. Both are not the best fit if you seek the best audio experience; you might consider additional speakers or a sound system. Give Feedback

"The QN90B delivers one of the brightest pictures we’ve ever seen, showcasing HDR content better than just about every LCD/LED TV on the market. If all you’re planning on doing is watching cable TV, broadcast channels, and a fair share of streaming shows or movies, the QN90B is sure to impress. All four of the QN90B’s HDMI 2.1 ports support 4K gaming at 120fps a centerpiece feature of the Xbox Series X and PlayStation 5."
