Definitely prefer the animations. However I would put sex sounds almost as important on the list. If I'm playing a game without sound I'll generally put on sexy asmr in the background.
Inclusion of animation sells me quicker on trying a game. If it's all images, then I usually want a larger quantity of images with the game. It's frustrating when a game has several paragraphs of text but just sits on one image for all of it.
Good animation is better, but often animations are bit crap tbh. Well done still renders or 2-3 frame "animation" is better than crappy animation. Especially if that gives faster update cycle.
