The Omni Series is notable for a number of reasons, not the least of which is Amazon's baked-in Fire TV interface. This affords access to every major streaming service, as well as a nifty selection of games and apps.

All models in the Omni Series also support hands-free Alexa operation, meaning you can say things like, "Alexa, turn on the TV," or "Alexa, watch Only Murders in the Building on Hulu," without ever touching the remote. I honestly didn't think that was a big deal until I started testing one of these TVs, but trust me: Hands-free commands are pretty awesome.

Features like that, along with the aforementioned app support, help give Fire TV the edge over Roku. And I say that as someone who tends to prefer the latter's interface. Right now, Fire TV is winning the smart-TV war.

And at $500, this 65-inch model is hard to beat.

If you have Amazon Prime, you’ll get free shipping on any of these TVs, of course. Not yet a member? No problem. You can sign up for your free 30-day trial here. (And by the way, those without Prime still get free shipping on orders of $25 or more, which mean any of these models will arrive without extra fees.)
