Graphic Style? Help!

I’m developing a game (mainly messing around with the story, at the moment) and I don’t know what style the game assets will be. I’m big on performance as I’m creating it for my fiancee and I to play together and her laptop isn’t all that great. The two things I’m eyeing are low poly models with hand painted textures or a cube/voxel style. I know she likes both but has a preference towards the hand painted style. Hand-Painted are usually considered “ugly” and “mobile-like” and it also takes a lot longer for me to do by myself. A voxel style is often considered a Minecraft rip-off and uncreative, but I could create a lot more by myself. So I’d like to know your opinions both regarding general preference and performance.

P.S. I have no clue if this is in the right place…
