I2P's garlic routing design is superior to onion routing regarding this particular attack due to the ability to shuffle packets, and being variable-latency (flows which don't need low latency can benefit from increased traffic-analysis resistance). However Tor has a big advantage in practice right now: lots of users, of every kind, to hide among. When GCHQ talked about "staining" in this context (as in the REMATION conference docs), by the way, they generally mean either a timing-based fingerprint (as here) or cookie-based fingerprint (unfortunately it seems to be used in at least two entirely different contexts, oh well).
