You really should consider the fact that there are parties who have a vested interest in making people doubt Tor. Tor is the best option we have by far and is currently far superior than i2p. It is designed to keep anonymity even with compromised nodes. Doing a deanonymizing attack is extremely hard and costly and only has a small chance of actually succeeding and that's before the new crypto algorithm roles out which makes this kind if attack pretty much impossible. Nothing is perfect but Tor does a pretty good job. It also has some of the most robust censorship resistance tools available and works in Russia and Iran. They solved the denial of service issue with a proof of work system a while back so performance wise Tor is now much better.

Meanwhile I2p still has issues with its design which the developers acknowledge on the website. This isn't meant to be hate against i2p but simply an analysis of the real world facts. I2p shouldn't be used anywhere where anonymity is critical as it is vulnerable to attack due to some outstanding issues with its design. Even outside out deanonymity, i2p still has issues with denial of service attacks and it doesn't have a simple solution for name resolution which is rather dangerous. I like it and concept and run my own node but I wouldn't rely on it for survival. Building a p2p network is really really hard which is why Tor uses a more centralized approach.
