what is """the best ™""" voice replication and text to speech solution?

Write now im trying SWivid/F5-TTS and without any training it works pretty well at taking some sample input of a couple minutes and generating a vocal clone. Rn I'm running a training session thats been going on for a few hours and it should be wrapping up shortly

>inb4 what features would you like
a GUI but i can work without it if its simple enough
>inb4 how big of a sample data set do you have
right now im training on just 5 minutes but i possibly have an available sample size of a few hours (i'd have to prune away some garbage)
>inb4 how accurate do you want it to be
as accurate as possible including emotional differences
>inb4 whats your GPU
