over a fire stick is a big improvement IMO. Roku (until the sale) was still better IMHO. But I still use all 3 depending on the room I'm in and the fire stick is the slowest of the 3 easily.
I have an Apple TV on the 2 TVs in the house(living room/bedroom). My LG OLED tvs are incredible, but I have literally never used its features besides turning it on. I just use the Apple TV remote and that box. Favorite thing is the dynamic backgrounds when we aren't watching to fill the room with color/light/warmth.
