The short answer
Both machines brew to the same independently tested standard, so this is not a quality comparison. Buy the OXO if you want a standard 45-second bloom, a rainmaker showerhead and a single-cup mode. Buy the Bonavita if you want the same certified brew from a machine whose entire interface is one button. Neither can be programmed to brew before you wake up.
What certification settles
The SCA's home-brewer certification tests brew temperature, contact time and the resulting extraction. Both of these pass it: the OXO at 197.6 to 204.8 F held through the cycle, the Bonavita at 195 to 205 F on a 1500 W heater.
That matters because most drip machines publish no temperature at all, and the ones that do rarely hold it. Once two machines are both certified, the remaining differences are about workflow rather than about whether the coffee is properly extracted.
Bloom: standard or optional
Fresh coffee releases carbon dioxide when it first meets water. If the machine floods the bed immediately, that gas pushes water around the grounds instead of through them.
The OXO pre-infuses for 45 seconds every time. The Bonavita offers pre-infusion as a mode. If you buy coffee from a roaster with a printed date, the OXO's automatic approach removes a decision; if you buy supermarket coffee that finished degassing months ago, neither setting changes much.
Basket shape and showerhead
The Bonavita uses a hanging flat-bottom basket: an even bed across a wide area, which is forgiving of a coarse or slightly uneven grind.
The OXO pairs its basket with a rainmaker showerhead that distributes water broadly rather than in a single stream. Both are attacking the same problem - getting water to arrive evenly - from different ends.

OXO Brew 9-Cup Coffee Maker
Mid tier · An SCA-certified drip brewer with a bloom cycle and a rain-style showerhead.
197.6-204.8 F held through the cycle, a 45-second bloom and a rainmaker showerhead.
The OXO Brew 9-Cup is an SCA Certified Home Brewer that holds 197.6 to 204.8 F through the whole cycle - not just at the start, which is where cheaper machines fall down.
Its bloom is a standard 45-second pre-infusion rather than an option you remember to select. On coffee roasted in the last two weeks that degassing step is the difference between an even extraction and one that channels around escaping CO2.
The rainmaker showerhead spreads water across the whole bed instead of drilling into the middle of it, which is the other half of even extraction in an automatic machine.
It brews a single cup as well as a full carafe, which the Bonavita's one-button design does not address, and its double-wall thermal carafe means no hotplate.
It is tall - measure cabinet clearance - its interface is fussier than a one-button machine, and there is more plastic in the build than the price suggests.

Bonavita Connoisseur 8-Cup
Mid tier · A one-button SCA-certified brewer with a flat-bottom basket and an optional bloom.
SCA certified at 195-205 F on 1500 W, with a flat-bottom basket and optional bloom.
The Connoisseur is SCA certified to the Golden Cup standard, with a 1500 W heater holding 195 to 205 F across a roughly six-minute cycle.
Its basket is a hanging flat-bottom design, which makes a shallower, more even bed than a cone - more forgiving of a slightly inconsistent grind or an uneven shower.
Pre-infusion is available as a mode rather than standard, so fresh beans get their bloom when you ask for it.
The carafe is a 1.3 L stainless thermal, so brewed coffee is never sitting on a hotplate being cooked.
The whole interface is one button: no clock, no timer, no delay start. That is the best thing about it or a deal-breaker, depending on your morning - see the Connoisseur review.

Capacity, honestly compared
The names are not comparable. The OXO's nine cups and the Bonavita's 1.3 L carafe are closer than the numbers suggest, because a drip machine's cup is a five-ounce serving rather than a mug.
In mug terms both machines make roughly three to five, which suits a household of two to four. Neither is a 12-cup machine for a crowd - for that, see best coffee makers for an office.
Neither has a timer
This is the shared limitation worth stating plainly: neither machine can be set the night before to brew at 6:30. If waking up to brewed coffee is the point of owning a drip machine for you, both are the wrong purchase.
Programmable machines exist at lower prices - they simply publish no temperature figures and carry no certification, which is the trade - see best coffee makers.
Which one is yours
- You buy freshly roasted coffee: the OXO, for the automatic bloom.
- You want the least interface possible: the Bonavita.
- You brew one cup as often as a carafe: the OXO's single-cup mode.
- Cabinet clearance is tight: the Bonavita - the OXO is tall.
- You want coffee waiting at 6:30: neither. Look at a programmable machine and accept the trade.
