This does not make much scientific sense.

Pfu and Pwo have the same DNA sequence (check Genbank or EMBL), 
therefore the same amino acid sequence and there should be no difference 
between the recombinant enzymes.

Any difference in performance should therefore be down to say reaction 
buffers or maybe the purification procedure on the enzymes.
