what is the best dental system to purchase for brushing, flossing, and periodontal care?

I have seen many different types of oral care systems on the market. Can someone suggest a system that they have tried, and found it to be truly beneficial? Is there a complete system for brushing, flossing(sonic)and includes a water pic. Thank You, serious answers please.

I really enjoyed the sonicare system. My dentist told me I had periodontal disease, and i immediately bought one, now, with regular flossing, i am fine.
