I like that it catches bots with no need for challenges but, how does it stack up against other Proof of Work solutions?

Truesign doesn't use PoW. The bot detection works by collecting network and browser signals.

The PoW solutions I've seen out there just add 1-2 seconds of delay before granting access to the whole site. It could work against random unsophisticaed crawlers but I don't see how that can stop determined bots.
