What are you mainly looking to track - stuff you lose often or something more valuable? Honestly, AirTag is more practical if you're in the Apple ecosystem, because tracking works across all your devices and the range is way better thanks to all those other people's iPhones. Tile works too, but the range is smaller and you need the app for it. If you only have Android, Tile's more your option, but generally I'd say AirTag wins if you have a choice.
Don't forget that both systems only work if you have your phone with you - without a network or Bluetooth nearby, even the best tracker won't help you. The practical trick: just combine both if you lose different things regularly. An AirTag on your keychain, a Tile in your laptop bag, and you use whichever works best for the situation. AirTag has worked more reliably for me in everyday use, but Tile is cheaper and honestly the better choice for people without an iPhone.
