Short answer: the JBL Stage 2 250B. It ranks #30 of 56 bookshelf speakers by sound quality at $349.95; the Q Acoustics 5020 ranks #42 and costs $1199, so there is not much of a tradeoff to weigh.
The case for the JBL Stage 2 250B: Consistent, EQ-able dips in the frequency response mean the tonal issues are at least correctable if you’re willing to use equalization. The tradeoff: The reviewer was “even less enthusiastic” about this one than its disappointing floorstanding sibling.
What the Q Acoustics 5020 offers: Attractively finished compact standmount with a 5-inch Continuous Curved Cone woofer and carefully engineered cabinet details. Watch for: Erin found the tonal balance distinctly too crisp, forward and treble-heavy: the top end is roughly 3-5dB elevated while the 1-3kHz region is recessed, so vocals change level unnaturally as they move through their range.
Buy the JBL Stage 2 250B. It ranks higher for sound quality than the Q Acoustics 5020 and costs less, so there is no real case for the other one.
If sound quality matters at all to you, skip the Q Acoustics 5020. It ranks near the bottom of the 56 bookshelf speakers, so look higher up the list instead.

JBL Stage 2 250B: $349.95 Amazon
Pros: Consistent, EQ-able dips in the frequency response mean the tonal issues are at least correctable if you’re willing to use equalization. Horizontal dispersion is reasonably wide and controlled (~50-60 degrees). The tweeter itself holds up fine under compression testing - it’s the midwoofer that gives out first.
Cons: The reviewer was “even less enthusiastic” about this one than its disappointing floorstanding sibling. A confusing, hard-to-place tonal signature - a lower-midrange dip creates a recessed, lacking-attack character that’s then partly offset by a rebound around 2-4kHz, so it reads as recessed and forward at different times depending on the material. Treble falls off sharply above 6-7kHz, same issue as the larger 280F. Multitone distortion at 96dB is genuinely poor - well over 3%, reportedly around 10% at some frequencies. Limited bass extension (F3 64Hz, F10 50Hz) means a subwoofer is basically required if used as main speakers. Compression sets in early on the bass/midwoofer at higher output. The reviewer explicitly recommends the similarly-priced Polk Reserve R200/R100 instead for anyone who wants a more linear, EQ-free sound.

Q Acoustics 5020: $1,199.00 Amazon
Pros: Attractively finished compact standmount with a 5-inch Continuous Curved Cone woofer and carefully engineered cabinet details. Erin found distortion well controlled at normal levels: below 1% down to about 50Hz at 86dB/1m. Its 87dB measured sensitivity is unremarkable rather than hard to drive, and it maintains acceptable output for typical 80-85dB listening. The rear port can be plugged for placement flexibility.
Cons: Erin found the tonal balance distinctly too crisp, forward and treble-heavy: the top end is roughly 3-5dB elevated while the 1-3kHz region is recessed, so vocals change level unnaturally as they move through their range. The shallow woofer crossover and steeper tweeter slope contribute to the off-axis discontinuity, while the port has a strong 1kHz resonance. Bass is limited: Erin measured F3 103Hz and F10 48Hz; at 96dB distortion reaches about 3% by 100Hz, and he bottomed the woofer when pushed hard. He preferred the less-expensive 3020i’s linearity and did not recommend the 5020 for neutral listening without EQ.
