I've been playing with Google blog search all morning. Here's my evaluation.
Responsiveness
Kicks ass! Technorati and the others have always struggled with response times that are not acceptable. Google blog search always responds sub-second.
Timeliness
Kicks ass! Technorati and the others often don't pick up links until the next day and Technorati sometimes a month later. Google blog search seems to pick up every link within one hour.
Coverage
Kicks ass! Technorati and the others pick up less than 70% of the links each (and sometimes much less). Google blog search seems to pick up every link (100%).
Overall
Game over! There's still tag search where Technorati is the leader, but I suspect Google will have a tag search shortly that will kick ass. If Technorati want to hang onto that pie, then I suggest Dave Sifry get to work on making a tag search that is responsive, timely and has full coverage.
Update: A chink in the armor, Google has not report this link. Mind you, neither has anybody else. Google missed it because the RSS feed is partial content. Anybody want a new reason to publish full content feeds?
I'm not as enthusiastic as you about Google, my choice still goes to Blogpulse at the moment :)

There's a Sorb by Date in plain view (top right).
