Short answer: the Genelec 8030C. It ranks #3 of 100 powered bookshelf speakers by sound quality, rated 4.6/5, at $1,750; the KEF LS50 Wireless II ranks #18, rated 4.3/5, and costs $2,999, so there is not much of a tradeoff to weigh.
The 8030C is the more accurate studio monitor. Audio Science Review measured a 1.9dB response span from 300Hz to 5kHz, smooth off-axis behavior and broad horizontal coverage, with bass reaching about 59Hz before falling 3dB. It has balanced inputs and bass, treble and room switches. Its bass headroom is limited, so a subwoofer helps for full-range listening, and it is sold individually.
The LS50 Wireless II is a complete streaming system. Its coaxial Uni-Q driver keeps tone consistent above and below the tweeter, it reaches 51Hz before falling 3dB on 380W per speaker, and it adds HDMI eARC, an analog input and streaming. Its placement presets are not true room correction.
Buy the Genelec 8030C. It is rated higher for sound quality than the KEF LS50 Wireless II and costs less, which makes it the one to get unless you need something the other one does better.

Genelec 8030C: $1,750 per pair B&H Photo Video eBay
Older model: the Genelec 8030A (ranked lower, estimated 4.4/5).
Same family: the Genelec 8010A (smaller bookshelf, rated 4.5/5), the Genelec 8020D (smaller bookshelf, ranked lower, rated 4.4/5), the Genelec 8040B (larger bookshelf, rated 4.3/5) and the Genelec 8050B (larger bookshelf, rated 4.4/5).
Pros: ASR’s Klippel measurements show a 1.9dB response span from 300Hz to 5kHz and smooth listening-window behavior. Predicted preference scores of 5.35 standalone and 7.60 with an ideal subwoofer support its high position for tonal accuracy. Broad, controlled horizontal radiation makes the balance relatively stable across a desk, and bass reaches -3dB around 56Hz. Measured bass extension of 59Hz (-3dB).
Cons: A dip around 2-3kHz remains, and vertical placement is less forgiving than the horizontal coverage suggests. Deep-bass headroom is limited; isolated high-output measurements at higher frequencies do not describe full-band loudness. The review found demanding bass material could cause audible distress beyond moderate levels. A subwoofer is useful for full-range monitoring.

KEF LS50 Wireless II: $2,999.00 per pair Amazon KEF Crutchfield eBay
Same family: the KEF LSX II LT (smaller bookshelf, ranked lower, rated 4/5), the KEF LSX II (smaller bookshelf, estimated 4.1/5) and the KEF LS60 (floorstanding, rated 4.8/5).
Pros: Erin’s measurements give preference scores of 5.43 standalone and 7.51 with an ideal subwoofer, with a -3dB point around 51Hz. The coincident Uni-Q layout helps preserve tonal consistency across horizontal and vertical listening positions. Low listening-window narrow-band deviation of 0.308 supports relatively clean midrange reproduction. HDMI eARC and streaming functions make it a capable all-in-one stereo system. Measured bass extension of 51.3Hz (-3dB).
Cons: The 3.0dB response span is good but not reference-leading, and dispersion still varies with frequency. Compact bass drivers limit deep-bass output. App placement adjustments are not the same as microphone-based automatic room correction. The price and primary/secondary architecture are practical trade-offs; neither driver geometry nor a single directivity statistic guarantees the best sound in every room.
