I think the key difference is cost, which can be split up into time, complexity, and mining fees.

On all three of these, even Wasabi 1.0 (released in October 2018) is better than the currently deployed whirlpool scheme.

Wasabi 1.1 made a significant improvement on all three (multi denomination batching), and Wasabi 2.0 impvoved all by another factor of 10x (arbitrary amount coinjoin).

Nowadays, Wasabi 2.0.4 is so mind blowingly fast, easy to use, and cheap, that it is a joke to compare it to whirlpool.
