Digital BW, The Print

I was wondering if anyone has done an A-B comparison between
Photoshops 10% Bicubic 
interpolation verses Photoshops Camera Raw plug-in. I am about to
print several digital 
files large and am curious about the best way to do the interpolation.

Also if there is a third party product out there that you think does
a better job than 
photoshop I am interested in hearing about that also, especially if
you have done a side by 
side comparison of all three methods.

Thanks

Steve
