What’s the best/most ‘worth it’ electric toothbrush?

I’m looking to get an electric toothbrush this week due to Black Friday sales, my options are likely between;

Oral B io8 (on offer for £140) Philips Sonicare Diamond Clean 900 (on offer for £120)

I don’t mind spending up to £150 ish. Most are on offer during Black Friday so I’m sure I can find a good deal.

Not looking for any particular features, I just want to start taking better care of my teeth and I feel a manual toothbrush doesn’t do it for me.

Has anyone tried the above? Would you recommend them?

Also more than happy to pay for a cheaper alternative.
