Short answer: the Rythmik F12, narrowly. It ranks #20 of 145 and pairs a sealed 12-inch servo with a 370W RMS amplifier at what the source calls excellent value. The SVS PB-1000 PRO gives up that placement (#37 of 145) for a ported 12-inch cabinet with a 325W RMS amplifier and guttural low extension to 17Hz.
On the Rythmik F12 side: Sealed 12-inch servo with 370W RMS offers excellent value.
The case for the SVS PB-1000 PRO: Ported 12-inch with 325W RMS delivers guttural low extension to 17Hz.
Buy the Rythmik F12. It is rated higher for sound quality, and the $590 you would save on the SVS PB-1000 PRO does not close the gap.
