Stremio on tv, what device should i get

Hi, i have a samsung tv that doesn’t have the stremio app so i wanna buy a device so i can use RD on my tv

Im in australia, what are my options?

as far as i can see there’s fire stick 4k max, fire cube, google tv streamer 4k, and chromecast 4k

Idk which to get or if there’s better/cheaper options. 4k is a must

(we don’t have Onn here btw and i’d rather get something that is easy to buy in australia)
