Are budget brands like Aquasonic actually as good as Oral-B or Sonicare?

For raw cleaning, high-trust reviewers at electricteeth.com and techgearlab.com say budget sonic brushes do a respectable job and represent strong value. However, r/askdentists threads flag inconsistent plaque-removal results, and the warranty, brush-head ecosystem, and long-term durability are weaker than the major brands. They are a great entry point, not a lifetime purchase.
