Short answer: the REL Acoustics HT/1510 Predator II. Both are rated 4.1/5 for sound quality (#98 and #86 of 143 subwoofers), and the REL Acoustics HT/1510 Predator II costs $2,199 against $2,999 for the SVS PB17-Ultra R-Evolution, with sound quality a draw, the lower price decides it.
Why pick the SVS PB17-Ultra R-Evolution: A giant ported 17 inch subwoofer that digs extremely deep and plays earth shaking movie bass in large rooms. The tradeoff: At 166.9 lbs (75.7 kg), or 167 lbs (75.8 kg), with recessed feet that leave little clearance, moving or repositioning this cabinet is a two-person job at minimum.
What the REL Acoustics HT/1510 Predator II does well: A sealed 15 inch home theater subwoofer with strong, punchy upper bass for movie effects and music. Watch for: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority.
Buy the REL Acoustics HT/1510 Predator II. Both are rated the same for sound quality, and it costs $800 less than the SVS PB17-Ultra R-Evolution.
