Price Comparison
The LG 65-Inch Class OLED evo AI 4K C5 Series Smart TV is priced at $1,396.99, making it about 61% cheaper than the Samsung 83-Inch Class OLED S90F 4K Smart TV, which is priced at $3,625.98. This significant price difference may appeal to budget-conscious consumers who are seeking high-quality television options without overspending. While the LG model offers a robust feature set at a lower price, the Samsung model is positioned as a premium option, reflecting its larger screen size and additional capabilities.
Picture Quality
In terms of picture quality, the LG OLED evo C5 utilizes advanced technologies to enhance viewing experiences. It features Perfect Black and Perfect Color technology, delivering stunning visuals through its 8.3 million self-lit pixels. The LG model also includes Dolby Vision, which significantly enhances color, contrast, and brightness. On the other hand, the Samsung OLED S90F boasts an AI processor that uses 128 neural networks to upscale content to 4K resolution, which contributes to impressive detail and picture clarity. Both TVs offer exceptional picture quality, but the choice may depend on personal preference regarding brightness and contrast capabilities.
Sound Quality
Sound quality is another area where both models excel, though they take different approaches. The LG C5 integrates Dolby Atmos technology, providing an immersive audio experience that complements its stunning visuals. This feature allows viewers to feel enveloped in sound, enhancing the overall cinematic experience. In contrast, the Samsung S90F also employs Dolby Atmos, but it takes it a step further with its Music Frame feature, which can offer clearer audio through its high-quality 3-way stereo speaker system. Users looking for a more robust audio setup may find the Samsung's offerings more appealing.
Gaming Features
For gamers, the LG C5 comes equipped with a 0.1ms response time and supports up to a 144Hz refresh rate, promising smooth gameplay with minimal lag. This makes it an excellent choice for both console and PC gamers. Additionally, it includes features like NVIDIA G-Sync and AMD FreeSync Premium, ensuring an optimal gaming experience. Conversely, the Samsung S90F also supports VRR gaming at up to 4K 144Hz, providing competitive performance for fast-paced gaming. Both models are designed to cater to gamers, but the LG may have a slight edge with its additional gaming technologies.
Smart Features
When it comes to smart features, the LG C5 is powered by the latest webOS 25 platform, which is designed to enhance user experience by simplifying content access and streaming capabilities. It includes Alexa built-in for voice control and smart home integration. The Samsung S90F, while also smart-enabled, focuses on customizable design and includes features like Q-Symphony, which harmonizes audio between the TV and compatible soundbars. Both TVs boast advanced smart capabilities, but the LG offers a more comprehensive streaming experience through its user-friendly interface.
Design and Aesthetics
The LG C5 features a nearly invisible bezel, allowing it to blend seamlessly into any space, which can be appealing for modern home aesthetics. It also offers an Art Gallery mode, allowing users to display artwork and photos. The Samsung S90F, on the other hand, is designed with a customizable exterior, allowing users to change the bezel color to match their décor. Both models prioritize design, but the choice may come down to personal preference between LG’s minimalist approach and Samsung’s customizable options.
Brand Reputation and Sales Rank
In terms of sales, the LG C5 holds a bestseller rank of 621, indicating a solid reception in the market. Samsung’s S90F, with a rank of 3,377, suggests it is less popular among consumers. Brand reputation can significantly influence purchasing decisions, and LG’s strong sales rank may indicate higher consumer trust and satisfaction. Although Samsung has a long-standing reputation for quality, the LG C5’s performance and features have evidently resonated well with buyers.
Which should you buy?
Ultimately, choosing between the LG 65-Inch Class OLED evo AI 4K C5 Series Smart TV and the Samsung 83-Inch Class OLED S90F 4K Smart TV comes down to individual needs and preferences. If you are looking for a high-quality television with exceptional picture and sound at a lower price point, the LG C5 is a compelling choice. However, if you desire a larger screen with customizable design features and robust audio capabilities, the Samsung S90F may be worth the investment. Each model excels in different areas, so consider what features are most important to you before making a final decision.
