Short answer: the Focal Alpha 65 EVO for better sound quality, the Presonus Eris Studio 8 for the lower price. The Focal Alpha 65 EVO ranks #49 of 66 powered bookshelf speakers at $499. The Presonus Eris Studio 8 ranks #57 at $462, $37 cheaper.
What the Focal Alpha 65 EVO offers: Very neutral, not quite as good as the Klasik 2020 in the midrange, but with better soundstage and instrument definition than the HS8 Watch for: Ignores sub-bass, and the LF/HF trim dials lack a center detent so getting back to flat takes trial and error.
What the Presonus Eris Studio 8 offers: More natural sounding and less fatiguing than the HS8 Watch for: Its documented strengths make it a credible option in this class.
Buy the Focal Alpha 65 EVO if sound quality is the priority over the price, or the Presonus Eris Studio 8 if the price is the priority over sound quality.
If sound quality matters at all to you, skip the Presonus Eris Studio 8. It ranks near the bottom of the 66 powered bookshelf speakers, so look higher up the list instead.

Focal Alpha 65 EVO: $499.00 Amazon eBay
Pros: ASR measured 42.5Hz -3dB extension, providing useful low-end reach for music. Analog input options and tonal controls make it straightforward to integrate into a studio, with a 5.71 ideal-subwoofer score indicating respectable but not leading tonality.
Cons: The measured 2.7dB response span from 300Hz to 5kHz and listening-window variation do not support a claim of reference-level neutrality. Placement and external correction may help. An anomalous distortion result from an individual sample should not be treated as a proven defect in every unit.

Presonus Eris Studio 8: $462 Amazon eBay
Pros: An 8-inch active monitor with XLR, TRS and RCA inputs and room-adjustment controls, providing flexible analog integration. Its cabinet and connection options suit a conventional studio setup.
Cons: The large cabinet requires substantial desk or stand space. Analog room-adjustment controls offer less flexibility than automatic calibration or parametric correction.
