they are pretty much the same thing, so I would say which ever you can get your hands on..

the pr3 is the ecu you use if you are using the cable speedo. the pwo is the one you use with the electronic speedo. so unless you have the jdm guage cluster, use the pr3. vtec will not engage under 3 mph unless you have a vtec controller. and the pwo ecu will not read any speed so the vtec wont engage.
