20K USHIO or 20K RADIUM?

Almost time to buy new lights for my D.E. 250 watt M.H. pendants (Electronic Ballast).
Was wondering if anybody had used the 20K USHIO or Radiums? or both.

Radiums are bluer (especially on an electronic ballast) and have more PAR than the ushios. then again they cost a bunch more. the ushios are more "VHOish" purplish. No real difference in "pop". they both have that down. Aquamaxx 14k has the radium look with less PAR (not less than the Ushio though) and half the price.
