An app with no animations at all is going to feel terrible. You can test this out yourself, if you have an Android you can set animation speed to 0x in the developer settings. It is jarring to see instant changes and it actually takes your brain a second to process what happened, and that process is probably slower than having the animation in the first place.
I have mine at 0.5x and that feels sufficient, still fast but I can see apps opening and closing etc.
