Which one is better, kinda confused about the difference apart from the remote with the google tv

I have the Chromecast with Google TV and its great
The remote is perfect, I can use it to turn on my TV, turn down the TV volume etc. plus it means you don't have to use your phone at all to watch stuff which is so much more convenient

based on some quick research the only downside for the Chromecast with Google TV compared to the Ultra is the Ultra can play Google Stadia but idgaf about that anyway so it was an easy win for the Chromecast Google TV
