Siblings in Paradigm's CI Pro series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | evenly matched | Much the same reach (86Hz vs 84Hz). |
| Amplifier needs | evenly matched | Similar sensitivity (93dB vs 94dB) - both want much the same power. |
| Size | depends | Paradigm CI Pro P3 v2 is easier to place; Paradigm CI Pro P5 v2 is bigger, which usually goes with fuller bass. Your room decides. |

depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
