These sit in different size classes, so this is not a straight ranking comparison. The Harman Kardon Citation 200 ranks #13 of 78 large speakers by sound quality at $130; the Sonos Era 100 ranks #12 of 16 powered desktop speakers by sound quality at $219.
The case for the Harman Kardon Citation 200: Deeper bass than any Onyx. The tradeoff: Overly boomy by default, you can short press the Bluetooth and volume down buttons simultaneously to decrease the bass, and the Bluetooth and volume up buttons simultaneously to increase it.
The case for the Sonos Era 100: RTINGS lists room correction tools and bass/treble adjustments as its real strengths, and its balanced midrange suits a wide range of genres, with wider stereo separation than the mono Sonos One SL it replaced thanks to two angled tweeters plus a 25% larger mid-woofer than the original Sonos One. The tradeoff: RTINGS’ own two listed cons are not loud enough for larger rooms and very little low-bass thump, so genres like EDM and hip-hop lack rumble even with the tone adjustments.
Buy the Harman Kardon Citation 200 at $130 for a large speaker, or the Sonos Era 100 at $219 for a powered desktop speaker instead.
Skip the Sonos Era 100 if sound quality matters to you. It ranks near the bottom of the 16 powered desktop speakers.
If water resistance matters to you, the Harman Kardon Citation 200 at IPX4 (splashing) holds up far better than the Sonos Era 100 at no water resistance.

Sonos Era 100: $219.00 each Amazon eBay
Pros: RTINGS lists room correction tools and bass/treble adjustments as its real strengths, and its balanced midrange suits a wide range of genres, with wider stereo separation than the mono Sonos One SL it replaced thanks to two angled tweeters plus a 25% larger mid-woofer than the original Sonos One. Alexa is built in with a far-field mic, and it ties into the wider Sonos S2 app ecosystem for multi-room audio.
Cons: RTINGS’ own two listed cons are not loud enough for larger rooms and very little low-bass thump, so genres like EDM and hip-hop lack rumble even with the tone adjustments. There’s no Google Assistant, the USB-C line-in needs a separately purchased adapter, and there’s no battery.
