Price Comparison

The LG 65-Inch Class OLED evo AI 4K C5 Series Smart TV is priced at $1,396.99, while the TCL 65-Inch Class S5 UHD 4K LED Smart TV with Fire TV is significantly more budget-friendly at $409.99. This means the TCL model is about 70% cheaper than the LG model. For consumers strictly focused on price, the TCL offers a compelling option without the hefty investment required for the LG. However, potential buyers should consider what features come with that lower price point, as the LG is packed with premium technology that may justify its cost.

Picture Quality

In terms of picture quality, the LG OLED C5 Series stands out with its OLED technology, boasting over 8.3 million self-lit pixels that deliver Perfect Black and Perfect Color, creating an ultra-realistic viewing experience. The LG also features Brightness Booster technology for enhanced brightness, making it suitable for bright rooms. In comparison, the TCL S5 uses a High Brightness LED backlight and supports various HDR formats, including Dolby Vision and HDR PRO+, offering vibrant images. However, the LG’s advanced OLED technology is generally recognized for superior contrast and color accuracy, which could be a significant factor for discerning viewers.

Sound Performance

The LG OLED C5 Series is equipped with Dolby Atmos, delivering immersive sound that surrounds viewers. This feature, combined with the FILMMAKER MODE, enhances the audio experience to match the filmmaker's intent. On the other hand, the TCL S5 also offers Dolby Atmos support, providing enhanced spatial audio capabilities. However, the LG's audio technology is specifically designed to match its high-quality visuals, ensuring an integrated experience. For audiophiles or movie enthusiasts, the LG may be the better choice, while the TCL still offers respectable sound quality for everyday viewing.

Gaming Features

When it comes to gaming, the LG OLED C5 Series excels with a 0.1ms response time and a native 120Hz refresh rate, offering a smooth gaming experience with no blurring or tearing. It also supports VRR up to 144Hz, making it an ideal choice for serious gamers. The TCL S5 includes a Game Accelerator 120 feature with VRR, which also aims to reduce lag during gameplay. While both TVs cater to gamers, the LG’s superior response time and refresh rate may provide a more competitive edge for those looking for the best performance in fast-paced games.

Smart TV Features

The LG OLED C5 Series comes with the LG webOS 25 platform, allowing seamless navigation and access to numerous streaming services. It includes features like Art Gallery mode and personalized content adjustments through its AI technology. Conversely, the TCL S5 integrates Fire TV for easy access to live TV, streaming services, and a wide array of entertainment options. Both smart TVs offer impressive capabilities; however, the LG's advanced AI features may appeal more to tech-savvy users who appreciate a tailored viewing experience.

Design and Aesthetics

Aesthetically, the LG OLED C5 Series boasts a nearly bezel-less design, allowing it to blend seamlessly into any room while doubling as a statement piece with its Art Gallery mode. The TCL S5 features a sleek, edge-to-edge FullView 360 metal bezel-less design, making it visually appealing as well. While both TVs have a modern look, the LG’s premium finish and design might be more appealing to consumers looking for a high-end visual centerpiece in their living space.

Brand Reputation and Sales Rank

The LG OLED C5 Series holds a sales rank of 621, indicating solid popularity among consumers, while the TCL S5 has a higher sales rank of 3187. LG has a long-standing reputation for producing high-quality OLED TVs, which may influence buyers who prioritize brand reliability and product performance. TCL, while a more budget-friendly option, is also gaining traction in the market with its innovative features. Buyers could consider brand reputation along with sales rank when making their choice, as these factors often correlate with customer satisfaction.

Which should you buy?

Deciding between the LG 65-Inch Class OLED C5 Series Smart TV and the TCL 65-Inch Class S5 UHD 4K LED Smart TV ultimately comes down to individual needs and budget. If you are looking for superior picture quality, advanced gaming features, and immersive sound, the LG OLED C5 Series, despite its higher price at $1,396.99, offers a premium experience that justifies the investment. However, if you are on a budget and still want a smart TV with good performance for everyday viewing and gaming, the TCL S5 at $409.99 presents a fantastic value. Each TV excels in different areas, so your choice should align with your specific preferences and usage scenarios.
