The Amazon Omni Series is somewhat more expensive but offers slightly better performance in a bright room and for news, talk, and reality TV. The 4-Series is less costly but has lower picture quality and performance for the same types of content. Both TVs have good contrast and very low input lag for gaming, though other gaming performance aspects are poor. If cost-saving is a priority and you mostly watch in darker environments, the 4-Series may be suitable. However, if you're willing to spend a bit more for improved brightness and better handling of daily content like news, the Omni Series could be a good choice. Keep in mind that neither of these models are particularly strong performers overall, so they are more budget-friendly options than high-quality investments. Give Feedback

"If you want a competent budget screen with some handy features, the Amazon Omni TV delivers an experience that punches well above its price tag. You’ll also get the benefit of Fire TV’s new UI right out of the box. It’s clean and simple to understand, plus it puts content first. In the picture-quality department, the Amazon Omni is a surprising star among some of its dimmer, less colorful rivals."

"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."
