Short answer: the SVS Prime Center. It ranks #69 of 98 center channel speakers by sound quality, rated 3.4/5, at $449; the ELAC Uni-Fi Reference UCR52 ranks #86, rated 3.3/5, and costs $799, so there is little reason to consider the other one.
What the SVS Prime Center does well: A three-way center with a 3.5” midrange between the 1” aluminum tweeter and two 5.25” woofers, which avoids the side-to-side cancellation of two-way centers: Erin’s Audio Corner measured the widest horizontal coverage of any center here, about ±75 degrees. Watch for: On-axis response is uneven (1.29dB average deviation), and the preference score is 3.34 without a subwoofer and 6.0 with one.
The ELAC Uni-Fi Reference UCR52 is the deeper-bass pick. A three-way center with a 1” soft dome tweeter mounted concentrically in a 4” aluminum midrange, between two 5.25” aluminum woofers. Its bass reaches about 60.1Hz before falling 3dB, against 71.8Hz for the SVS Prime Center. The catch: On-axis response is among the least even of any center here (1.34dB average deviation), and its listening window spans 5.7dB from 300Hz to 5kHz, the widest spread of any center here, which colors voices.
Buy the SVS Prime Center. It is rated higher for sound quality than the ELAC Uni-Fi Reference UCR52 and costs less, which makes it the one to get unless you need something the other one does better.

ELAC Uni-Fi Reference UCR52: $799.00 each Amazon eBay
Pros: A three-way center with a 1” soft dome tweeter mounted concentrically in a 4” aluminum midrange, between two 5.25” aluminum woofers. The concentric driver keeps dispersion even in every direction: Audio Science Review measured about ±55 degrees both horizontally and vertically, so it works above or below a screen. Bass reaches 60.1Hz (-3dB) and about 44Hz (-10dB). Measured bass extension of 60.1Hz (-3dB).
Cons: On-axis response is among the least even of any center here (1.34dB average deviation), and its listening window spans 5.7dB from 300Hz to 5kHz, the widest spread of any center here, which colors voices. Sensitivity is a low 85dB. Preference score 3.40 without a subwoofer.
