Tor is an implementation of i2p. Basically it’s a new protocol that obfuscates everything end to end.
On public trackers you’d be fine since it’s public and ip doesn’t matter. But on private trackers, they usually need your ip to track your activity on the tracker, but with i2p it would be nigh impossible to do so.
If you only watch English content, 100%. But if you are into foreign language stuff then private trackers do have some scene releases that aren’t available on public ones.
