Both are important to me. It just really comes down to the game. The new Spider-man, I'd rather have a game like that just look as pretty as possible so I'll take the 4K, HDR and raytracing at 30fps. If you somehow could get all of the same visuals AND 60fps or more though, I would take that every time.
30fps and even 60fps is a compromise and limitation of the hardware. If you play a fast paced shooter like DOOM, it wouldn't be the same at 30fps or even 60fps. You need that butter smooth and high frame rate and that's what makes it special. If I'm playing competitively or a FPS, I want the highest frame rate possible. If I'm playing a cinematic game or open world game, I'd rather it look nice than have a high frame rate but if I could have both, there's no way I would choose a lower frame rate intentionally.
Games aren't movies and I see no benefit to a lower frame rate. As mentioned before, it's a hardware limitation and if developers could have all games run at 144fps, they would.
