My kitties love toys -- most toys. Favorites are plush small stuffed things (that don't usually stay stuffed for too long) with or without catnip, or anything with feathers. I have wands and they are a hit, but my cats like their regular toy mouse with a long sisal string tied to it better. They can chase the mouse end or the string end. Jingle balls are ok. The boy has a toy I made by stuffing a cut-off leg of a pair of sweatpants with catnip. It's big enough he can wrestle it. One thing I notice the female especially likes are toys with dangly parts, like the mice with pom-pom balls fir feet, attached with a suede string. Something she can tug at, or grab to carry it. They will both retrieve and chase toys.
The male will chase a laser pointer for ages, especially if it hugs the edges of the room and tries to hide under furniture or in shoes. The female looks at him like he's stupid to fall for it. If she can't get her teeth in it, it's no good. But she LOVES crinkly plastic, packing tape, etc. Plastic bags to a lesser degree.
The male loves elastic rubber. He will steal rubber bands (which I try to keep locked away because he WILL eat them) and used to be really bad about stealing my hair bands. I saw a package of colorful loopy hairbands at the store and bought him some -- they are his favorite toys and he can't swallow them.
My cats don't much care for independent toys either. But the love the climbing trees and scratching posts I made them.

It seems to me the materials can attract my cats more than anything else. Shape only matters as to whether it's easily grab-able, carry-able, or can be wrestled with.
