If I was buying for business than the Intel drives would be my choice.  
They are clearly the quality leader.  For instance, Intel has tweaked 
their firmware to optimize for small IOs.  The X25-E and X25-M are class.
We agree here I think.

For home use where it is *my* money I am willing to have a little faith 
in order to save a couple hundred dollars.  I realize that OCZ and its
controller supplier will be shipping firmware updates.  But don't kid 
yourself, so is Intel.

BTW, what OCZ did to increase speed was to increase the cache size in 
their large capacity high end Vertex models.  This wouldn't help my 
30 GB model.
