I mostly have this gemini assitant because google esentially added it for me. Of course i tried a bit of gpt. My advice is that, if they're good there's a chance that they many not be anymore in the future. Or not how you expect them to be. We have to make it good too, but right now the world is hooked with AI.
I have seen to much ai spam to care for ai images, there is this youtube series with ai assisted animations (monoverse, neural viz), that is the only good use of ai i ever seen so far in media creation. But, other than that, it's getting distopian out there.
