FireTV 4K is full of ads and is slow; also, the 3rd party apps vary greatly. Nebula crashes a lot, and Crunchyroll is a hot mess. I was thinking of replacing it with an Apple TV, but since I’d like a device for indie games and Honkai Star Rail, I’ve decided to get a mini PC instead. It’s arriving today, so I can’t tell you how it is, but price wise, it’s $185 and it runs on an Intel N100, so it’s energy efficient.
