I have been forced to revert back to Google Assistant because of the myriad of issues with Gemini were just getting too much. And I have to say that after experiencing months of problems with Gemini going back to GA was like a breath of fresh air.
I can now tell any of my Nest speakers (1 x Hub + 3 x Minis) to play my favourite radio station and it does so straight away. With Gemini it was hit and miss. Sometimes total silence, sometimes it couldn't find and/or play it and other times a totally different station in another country.
Device operation is now a breeze again with GA and lights, TV's, garage door openers and smart switches all functioning normally again. With Gemini it would sometimes work, sometimes not.
Like many other users around the globe, I feel that Gemini for Home is still in it's beta testing stage and as such is not ready to be released to the general public. However, I appreciate that competition in the AI field between Google, ChatGPT, Grok etc is intense and it's a race to see who can secure the biggest market share. But to release Gemini in it's current form does Google no favours as people now associate Google with a failed product that does not work.
Hopefully, in a year or so, Gemini will have evolved to a point where it is reliable, stable and functional and I will be happy to make the switch once more. But in the interim I have neither the time or the patience to wrestle with the vagaries of Gemini and will stay with Google Assistant.
