It's actually not that great in either situation. The Stone Bones line has two problems:
1) if you miss, it doesn't do anything
2) even if you hit, it depends on your opponent hitting you the round afterwards.
As a general rule, anything that requires your opponent to do a certain thing is a lot less useful than something that works no matter what (which is also why a maneuver which boosts your to-hit is usually better than a maneuver which boosts your AC).
The first-level maneuvers I usually pick for a level 1-2 Warblade are:
1. Steely Strike
2. Steel Wind
3. Charging Minotaur
4. Moment of Perfect Mind
Possibly swap one of those for Leading the Attack or Wolf Fang Strike if you need to fill pre-reqs.
