Tell me your laptop/water bottle sticker preferences!

I'm in the hobbybusiness of making and selling stickers! Looking for opinions about designs and use:

Given the option, would you rather use a sticker on a laptop or water bottle? Or are they more of a collectible thing that you'd rather not stick anywhere?

Would you prefer stickers with designs from recognizable games/movies/etc or stickers with interesting original designs? Do you prefer something cartoony/cute or artistic and pretty?

Would you rather buy stickers from an external site like StickerMule and Redbubble or straight from an Artist Alley table?
