I test TVs for a living — these are the Prime Day TV deals I'd actually buy from $159

This 55-inch Insignia TV is going to be one of the cheapest you're going to find during Prime Day. Thanks to its built-in Fire TV features, you can also stream all your favorite shows and movies and control them with your voice thanks to full Alexa support.

The Toshiba C350 4K Fire TV may seem inexpensive, but it packs a lot of features for its price. It supports Dolby Vision/HDR10/HLG content and it also houses Amazon's Fire TV OS, so you can browse through dozens of streaming apps and even control your TV via the included voice remote.

The QM5K has built-in Google TV features for all of your streaming needs, plus Dolby Vision support. Its handiest feature is its Mini-LED backlighting, which is difficult to find at this price point. If you're going to shop in this price range, I recommend going with the QM5K over a super-cheap TV from a brand like Insignia or Onn.

The TCL QM7K is perfect for folks who want to upgrade to a truly impressive TV without breaking the bank. It's also an especially good TV for gamers on a budget, thanks to an impressive array of gaming enhancements.

This Prime Day, the only small-sized OLED TV I'd consider is the 48-inch Samsung S90F. It's on sale for a cool $797 — almost $600 off its usual price. In addition to its sensational, OLED-driven performance, the S90F also comes with a heaping helping of high-end gaming features and Samsung's Smart Hub streaming software.

Hisense's newest, mid-range set offers a taste of high-end performance without the sky-high price. In addition to bright, punchy Mini-LEDs and QLED color, the U7SF also offers a thorough slate of gaming- and streaming-related features.

The 65-inch XR8B blends Sony's top-notch picture processing with an array of features for streaming and gaming. This includes built-in Google TV and support for 4K gaming at 120Hz.

The Samsung S90F OLED TV is an enticing option, offering a 144Hz refresh rate on one of Samsung's best upscaling processers. It also has Tizen OS, which is built with tons of free channels, not to mention several cloud gaming services, and a full Gaming Hub for all your settings in one place. The S90F also has tons of AI baked into it, like an AI Sound Pro that boosts audio dramatically.
