The Apple TV Siri Remote (~£59)
Ships with the Apple TV 4K (~£199).
Has a “Touch surface” that can be both too easy and too hard to trigger, which gets super fun when navigating menus.
Has IR TV volume control but no standby control, so you still need the TV remote.
The Alexa Voice Remote for Fire TV (~£30)
Ships with the Fire TV Stick 4K (~£50).
Has clicky directional buttons so if you want to move left once, you just press left once.
Has IR TV volume and standby control, eliminating day-to-day need for my TV remote.
So
Price is often a proxy for value. They’re definitely not the same thing.
Alas both of them have microphones…
