Oral B VS Sonicare

Who's used both? Which do you prefer and why? I currently use an Oral B iO7 but wondering whether to try a Sonicare unit as it's been suggested that they can be better for getting in-between teeth and improving periodontal health. The Oral B units are 'plaque blasters' in comparison. I would love to know the outlook of people's dentists or hygienists having switched from one to the other...

I use the Oral B and my wife uses Sonicare hers quit but she said she preferred the Sonicare and bought a new one. I know the Sonicare gets better ratings but I prefer my Oral B.
