Bullet and ODE are both open source, so you can benefit from both. 

Bullet collision detection is better then what is in ODE (OPCODE etc),
but ODE quickstep is a more mature constraint solver. They can be combined.
Work is on its way (albeit slowly) to bring in good parts of Bullet into 

You can tell your programmer to consider discussing any issues with ODE 
and/or Bullet on
the Bullet physics forum, http://bulletphysics.com
This Bullet physics forum is more technical and for physics developers, 
rather then physics users. 

Hope this helps,
