Best english TTS voice?

I’ve been using VoiceRSS for about a year but I’m not really satisfied with the voice so I thought I should have a look at the options. But before I start trying them all out I thought I should ask and see if anyone already done that and what the outcome was?

I’ve tried Google’s voice but that’s nowhere near the excellent quality of the Google Home assistants voice, that would otherwise been perfect.

I like Amazon’s Polly
