Considering your budget is a primary factor, if you're looking to save money, the Amazon 4-Series offers a budget-friendly option, but you'll compromise on picture and gaming quality, as it has poor scores across the board except for a fair bright room performance. On the other hand, the Sony X90J, while more expensive, provides a significant upgrade in overall viewing experience with good to very good scores in most categories, including gaming, sports, and movies, making it a better choice if you frequently watch these types of content. However, it has a poor viewing angle, meaning it's not the best pick if you have a wide seating arrangement. If you plan to use the TV in a bright room, both TVs have decent performance, with the Sony being better. If sound quality is a concern, both TVs offer fair audio performance, though neither is exceptional, and you may consider adding external speakers or a soundbar. The Sony X90J also has better motion processing and is equipped with a 120Hz panel, which is advantageous for gaming and sports, and it supports more advanced HDR formats like Dolby Vision, making it a better fit for future-proofing and enjoying high dynamic range content.

"The attraction here is that the 4-Series uses Amazon’s Fire TV interface. Picture quality is good but unexceptional. At the discounted prices, which can seemingly be had regularly, they are better value."
