Philips Sonicare ProtectiveClean 6100 vs Waterpik Aquarius WP-660
Verdict: These products serve fundamentally different purposes—one is a sonic toothbrush and the other a countertop water flosser—so they are complementary rather than direct competitors. The Philips Sonicare ProtectiveClean 6100 leads in portability and daily brushing efficacy per CNET and Wirecutter evaluations while the Waterpik Aquarius WP-660 provides superior interdental cleaning backed by ADA acceptance. Users needing both functions should consider owning one of each instead of choosing between them.
Winner: Philips Sonicare ProtectiveClean 6100
Philips Sonicare ProtectiveClean 6100: 8/10
Waterpik Aquarius WP-660: 7/10
