Best streaming device for TV

[Yetiyoga]

I have a smart TV but sadly it only has the catch up channels and Netflix. I have amazon prime as well as Netflix and Disney plus so hoping for a device to plug in that I can access all on. Any ideas?

There is the amazon firestick, roku stick? How do these compare?
Any others I've not thought of?

A chromecast. I used that to stream all catch up tv, prime video, netflix, starzplay and now tv from my phone. You can get second hand ones from shops like CEX, they're not expensive.

Thanks. I will have a look at them online

Roku is good
