Short answer: the Micca RB42. It ranks #41 of 56 bookshelf speakers by sound quality at $159.99; the Q Acoustics 5020 ranks #42 and costs $1199, so there is not much of a tradeoff to weigh.
On the Micca RB42 side: Curved cabinet fit and finish look closer to a $400-500 speaker than a $150 one. Set against that: CEA2034 spinorama shows significant peaks and valleys in the on-axis and listening-window response starting a few kHz up.
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 Micca RB42. 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.

The Two Speakers In Full
Micca RB42: $159.99 Amazon
Pros: Curved cabinet fit and finish look closer to a $400-500 speaker than a $150 one. Rated for a wide 15-100W amplifier range with 4-8 ohm compatibility, giving flexibility with modest amplification.
Cons: CEA2034 spinorama shows significant peaks and valleys in the on-axis and listening-window response starting a few kHz up, with excess high-frequency energy the reviewer found fatiguing over time despite an initial impression of “detail.” Off-axis response diverges heavily from on-axis, meaning tonality shifts with room and listening position in ways EQ can’t correct. Distorts and the woofer visibly flaps under moderate volume; low 83dB sensitivity makes it a harder amplifier load than its size suggests.

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.
