Is a Sonicare or an Oral-B better for cleaning?

It is genuinely contested. Specialist-community threads (notably r/BuyItForLife) split between the two: Sonicare uses high-frequency sonic vibration while Oral-B uses oscillating-rotating heads, and individual reviewers report better results from each. The consensus is that brushing technique and consistency matter more than the technology, and both are well-regarded by dentists referenced in those threads. Pick based on feel and replacement-head cost.
